The ECG detection method provided by the embodiment of the present application is described below by taking the wearable device as an example.

Fig. 1 shows a block diagram of a wearable device provided in an embodiment of the present application, and as shown in fig. 1, the wearable device provided in an embodiment of the present application includes a processor 110, a memory 120, an input unit 130, a display unit 140, a sensor 150, an audio circuit 160, a wireless communication module 170, a power supply 180, an electrode 190, and other components. Those skilled in the art will appreciate that the wearable device structure shown in fig. 1 does not constitute a limitation of the wearable device, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.

The following describes each component of the wearable device in detail with reference to fig. 1:

the processor 110 is a control center of the wearable device, connects various parts of the entire wearable device by various interfaces and lines, and performs various functions of the wearable device and processes data by running or executing software programs and/or modules stored in the memory 120 and calling up the data stored in the memory 120, thereby performing overall monitoring of the wearable device. Alternatively, processor 110 may include one or more processing units; preferably, the processor 110 may integrate an application processor, which mainly handles operating systems, user interfaces, application programs, etc., and a modem processor, which mainly handles wireless communications. It will be appreciated that the modem processor described above may not be integrated into the processor 110.

The memory 120 may be used to store software programs and modules, and the processor 110 executes various functional applications and data processing of the wearable device by running the software programs and modules stored in the memory 120. The memory 120 may mainly include a storage program area and a storage data area, wherein the storage program area may store an operating system, an application program required by at least one function (such as a sound playing function, an image playing function, etc.), and the like; the storage data area may store data (such as audio data, a phone book, etc.) created according to the use of the wearable device, and the like. Further, the memory 120 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device.

The input unit 130 may be used to receive input numeric or character information and generate key signal inputs related to user settings and function control of the wearable device. Specifically, the input unit 130 may include a touch panel 131 and other input devices 132. The touch panel 131, also called a touch screen, can collect touch operations of a user (such as operations of the user on the touch panel 131 or near the touch panel 131 by using any suitable object or accessory such as a finger, a stylus, etc.) thereon or nearby, and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 131 may include two parts, i.e., a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 110, and can receive and execute commands sent by the processor 110. In addition, the touch panel 131 may be implemented by various types such as a resistive type, a capacitive type, an infrared ray, and a surface acoustic wave. The input unit 130 may include other input devices 132 in addition to the touch panel 131. In particular, other input devices 132 may include, but are not limited to, one or more of a crown, volume control keys, switch keys, and the like.

The display unit 140 may be used to display information input by or provided to the user and various menus of the wearable device. The display unit 140 may include a display panel 141, and optionally, the display panel 141 may be configured in the form of a Liquid Crystal Display (LCD), an organic Light-Emitting diode (RLED), or the like. Further, the touch panel 131 can cover the display panel 141, and when the touch panel 131 detects a touch operation on or near the touch panel 131, the touch operation is transmitted to the processor 110 to determine the type of the touch event, and then the processor 180 provides a corresponding visual output on the display panel 141 according to the type of the touch event. Although in fig. 1, the touch panel 131 and the display panel 141 are two separate components to implement the input and output functions of the wearable device, in some embodiments, the touch panel 131 and the display panel 141 may be integrated to implement the input and output functions of the wearable device.

The wearable device may also include at least one sensor 150, such as a capacitive sensor, a motion sensor, and other sensors. Specifically, the capacitance sensor is used for detecting capacitance between a human body and the wearable device, and the capacitance can reflect whether the human body is in good contact with the wearable device. As one of the motion sensors, the accelerometer sensor can detect the magnitude of acceleration in each direction (generally three axes), detect the magnitude and direction of gravity when stationary, and can be used for applications (such as horizontal and vertical screen switching, related games, magnetometer attitude calibration), vibration recognition related functions (such as pedometer, tapping), and the like, for recognizing the attitude of the wearable device; as for other sensors such as a gyroscope, a barometer, a hygrometer, a thermometer, and an infrared sensor, which can be configured on the wearable device, the description is omitted here.

Audio circuitry 160, speaker 161, microphone 162 may provide an audio interface between the user and the wearable device. The audio circuit 160 may transmit the electrical signal converted from the received audio data to the speaker 161, and convert the electrical signal into a sound signal for output by the speaker 161; on the other hand, the microphone 162 converts the collected sound signal into an electrical signal, converts the electrical signal into audio data after being received by the audio circuit 160, and then inputs the audio data to the processor 180, or outputs the audio data to the memory 120 for further processing.

The wireless communication module 170 may be configured to support data exchange between the wearable device and other electronic devices, including BT, WLAN (e.g., wi-Fi), zigbee, FM, NFC, IR, or general 2.4G/5G wireless communication technologies.

The wearable device also includes a power source 180 (e.g., a battery) for powering the various components, which may preferably be logically connected to the processor 110 via a power management system, such that the power management system may be used to manage charging, discharging, and power consumption.

The electrode 190 may include at least two electrodes through which the human body and the wearable device form a loop when a body part of the user is in contact with the electrode 190. Because the electrical charge in the human body generates an electrical signal during the beating of the heart, the electrode 190 can capture the electrical signal of the skin of the human body. The processor determines physiological parameters of the user, e.g., ECG detection data, from electrical signals of the human skin captured by the electrodes.

The ECG detection method provided in the embodiment of the present application is described below with reference to the wearable device shown in fig. 1.

As shown in fig. 2, a first embodiment of the present application provides an ECG detection method including:

s101: ECG detection data of a wearable device and first wearing information of the wearable device are acquired.

Wherein the ECG detection data is generated from the acquired electrical signals of the human skin. ECG detection data is used to characterize the potential difference between two limbs of the human body, for example, between the left upper limb and the right upper limb, between the left lower limb and the right upper limb, or between the left lower limb and the left upper limb. Specifically, two electrodes are arranged on the wearable device, two limbs of a human body respectively contact the two electrodes, so that a loop is formed between the human body and the wearable device, the electrodes can capture electric signals generated by the skin of the human body, and the processor generates ECG detection data according to the generated electric signals. Exemplarily, as shown in fig. 3, the wearable device is an electrocardiograph watch, the two electrodes are respectively disposed on a bottom cover and a crown of the watch, when a user wears the electrocardiograph watch with one hand, the wearable device is in contact with the bottom cover of the watch, and then can contact one of the electrodes, and the other hand presses the crown, and then can contact the other electrode, so that a loop is formed between the human body and the electrocardiograph watch, and ECG detection data is acquired. It can be understood that if the electrode arranged on the bottom cover of the watch is the positive electrode, the electrode arranged on the crown is the negative electrode, the user wears the electrocardio watch by the left hand and presses the crown by the right hand, so that the left hand can be in contact with the positive electrode, the right hand can be in contact with the negative electrode, and a loop is formed between the human body and the electrocardio watch. The left hand contacts the positive electrode and the right hand contacts the negative electrode to carry out ECG detection, namely simulation I leads in electrocardiogram leads are obtained, and the simulation I leads are used for obtaining electric signals representing potential difference between the left upper limb and the right upper limb.

The first wearing information is wearing position information of the wearable device, and the processor calculates the first wearing information according to the motion information acquired by the motion sensor. Illustratively, if the wearable device is an electrocardiographic watch, the first wearing information is wearing hand information of the electrocardiographic watch, for example, left-handed wearing or right-handed wearing.

In a possible implementation manner, when the processor detects that the wearable device is worn according to the wearing information acquired by the motion sensor or the infrared sensor, the processor calculates first wearing information according to the motion information. When the processor receives the electrical signals acquired by the electrodes, ECG detection data is generated from the electrical signals.

S102: second wearing information is calculated from the ECG detection data.

In one possible implementation, the second wearing information is calculated from a waveform map corresponding to the ECG detection data. Illustratively, fig. 4 is a waveform diagram generated from ECG detection data acquired in a simulated I-lead test, i.e., a waveform diagram of the potential difference between the left and right upper limbs when the left hand is in contact with the positive pole and the right hand is in contact with the negative pole. Selecting the wave bands of which the waveform diagram meets the preset condition, for example, selecting peaks with amplitude values larger than the preset amplitude in fig. 4, for example, 4 peaks in total of b, f, j and n, wherein a v-p-v wave band formed by each peak and two wave troughs on two sides of each peak is the wave band meeting the preset condition, namely, the wave band abc, the wave band efg, the wave band ijk and the wave band mnr. The wave troughs with the absolute value of the amplitude value larger than the preset amplitude in the oscillogram are selected, for example, 4 wave troughs are formed by c, g, k and r, and the p-v-p wave band formed by each wave trough and the wave crests on two sides of the wave trough is the wave band meeting the preset conditions, namely, the wave band bcd, the wave band fgh, the wave band jkl and the wave band nrs. And calculating second wearing information according to the curve length between two adjacent wave troughs in the selected wave band, the curve length between two adjacent wave crests, the amplitude value of each wave crest and the amplitude value of each wave trough. For example, in the band selected in fig. 4, the second wearing information is calculated based on the curve length between ac two troughs, the curve length between eg two troughs, the curve length between ik two troughs, the curve length between mr two troughs, the curve length between bd two peaks, the curve length between fh two peaks, the curve length between jl two peaks, and the curve length between ns two peaks, that is, the curve length of each band, the amplitude value of each peak, and the amplitude value of each trough.

In one possible implementation manner, in a wave band satisfying a preset condition, selecting a maximum value in a curve length between two adjacent troughs, a maximum value in a curve length between two adjacent peaks, a maximum value in a peak amplitude value, and a maximum value in a trough amplitude value; if the maximum value in the curve length between two adjacent wave troughs is greater than the maximum value in the curve length between two adjacent wave crests, and the maximum value in the wave crest amplitude value is greater than the maximum value in the wave trough amplitude value, the wearing part corresponding to the second wearing information is consistent with the preset standard wearing part. For example, in FIG. 4, the wavelength band with the longest curve length among all the v-p-v bands is selected, that is, the wavelength band with the longest curve length is selected from the bands abc, efg, ijk and mnr, the wavelength band with the longest curve length among the p-v-p bands is selected, that is, the wavelength band with the longest curve length is selected from the bands bcd, fgh, jkl and nrs, and the size of the wavelength band with the longest curve length among the v-p-v bands is compared with the size of the wavelength band with the longest curve length among the p-v-p bands; selecting the maximum value of the amplitude values in b, f, j and n 4 wave crests, selecting the maximum value of the absolute values of the amplitude values in c, g, k and r 4 wave troughs, if the wave band with the longest curve in the v-p-v wave band is larger than the wave band with the longest curve length in the p-v-p wave band, and the maximum value of the amplitude values in the wave crests is larger than the maximum value of the absolute values of the amplitude values in the wave troughs, the wearing part corresponding to the second wearing information is consistent with the preset standard wearing part, and if not, the wearing part corresponding to the second wearing information is inconsistent with the preset standard wearing part.

For example, for an electrocardiogram watch, the positive electrode is located at the bottom cover of the electrocardiogram watch, and the left-hand contact positive electrode is set to be in a standard wearing mode, that is, the standard wearing part is worn by the left hand. The second wearing information is wearing location information, for example, left-handed wearing or right-handed wearing. Illustratively, as shown in fig. 4, if the preset standard wearing part is left-handed wearing, the band with the longest curve in the v-p-v bands in the ECG detection data is larger than the band with the longest curve in the p-v-p bands, and the maximum value of the amplitude value in the peak is larger than the maximum value of the absolute value of the amplitude value in the trough, then the second wearing information is consistent with the standard wearing part and left-handed wearing, otherwise right-handed wearing.

In other possible embodiments, in the bands satisfying the preset condition, the second wearing information may be calculated based only on the maximum value in the curve length between two adjacent valleys and the maximum value in the curve length between two adjacent peaks, or calculated based only on the maximum value in the peak amplitude value and the maximum value in the valley amplitude value, or calculated based on the sum of the lengths of all the v-p-v bands and the sum of the lengths of all the p-v-p bands. For example, in the waveform diagram of the ECG detection data, when it is satisfied that the maximum value of the curve lengths between the adjacent two troughs is larger than the maximum value of the curve lengths between the adjacent two peaks, it is determined that the wearing position corresponding to the second wearing information coincides with the preset standard wearing position. Or when the maximum value in the peak amplitude value is larger than the maximum value in the trough amplitude value, the wearing part corresponding to the second wearing information is judged to be consistent with the preset standard wearing part, or when the sum of the lengths of all the v-p-v wave bands is larger than the sum of the lengths of all the p-v-p wave bands, the wearing part corresponding to the second wearing information is judged to be consistent with the preset standard wearing part.

S103: and judging whether the first wearing information meets a preset credible condition.

Specifically, when the wearable device is detected to be in a wearing state, first wearing information is calculated according to motion information collected by the motion sensor. When the first wearing information is calculated, the motion state of the wearable device is calculated according to the motion information collected by the motion sensor, and if the motion states of the wearable device in the preset time are all in a static state, the first wearing information is not in accordance with the preset credible condition, namely the first wearing information is not credible. For example, if it is detected that the electrocardiograph watch is in a static state within five minutes according to the motion information acquired by the motion sensor after the electrocardiograph watch is worn, the first wearing information does not meet the preset credible condition. Or if the obtaining time of the first wearing information is longer than the preset time, the first wearing information does not accord with the preset credible condition. For example, if the first wearing information is acquired 12 hours ago, that is, the first wearing information is not changed within 12 hours, the first wearing information is not trusted. Otherwise, the first wearing information meets the preset credible condition, namely the first wearing information is credible.

S104: and if the first wearing information accords with the preset credible condition, judging whether the first wearing information and the second wearing information are consistent.

For example, if the first wearing information meets the preset credible condition, the first wearing information is worn by the left hand, and the wearing part determined according to the second wearing information is the left hand, the first wearing information and the second wearing information are consistent.

S105: and if the first wearing information is consistent with the second wearing information, determining the wearing part according to the consistent detection result.

Specifically, if the first wearing information is identical with the second wearing information, the detection result is credible, and the wearing part is determined according to the identical detection result of the first wearing information and the second wearing information, for example, left-hand wearing or right-hand wearing.

S106: and judging whether the wearing part determined according to the consistent detection result is consistent with the preset standard wearing part or not.

S107: and if the wearing part determined according to the consistent detection result is consistent with the preset standard wearing part, generating and displaying a oscillogram corresponding to the ECG detection data.

Specifically, if the wearing part determined according to the motion sensor and the ECG detection data is consistent with the preset standard wearing part, a corresponding oscillogram is generated according to the ECG detection data, and the oscillogram is displayed on a display interface of the wearable device.

For example, the wearable device is an electrocardiographic watch, and the ECG detection data is calculated by subtracting the positive electrical signal from the negative electrical signal. The preset standard wearing part is worn by a left hand, and when the left hand is worn, the left hand is in contact with the anode, and the right hand is in contact with the cathode. The ECG test data for the standard waveform is the electrical signal detected on the left hand minus the electrical signal detected on the right hand. If the wearing part determined by the motion sensor and the ECG detection data is worn by the left hand, namely the left hand is in contact with the anode, and the right hand is in contact with the cathode, the electrical signal of the anode minus the electrical signal of the cathode is the electrical signal detected on the left hand minus the electrical signal detected on the right hand, namely the ECG detection data is the ECG detection data corresponding to the standard waveform, and a corresponding waveform diagram is generated and displayed according to the ECG detection data.

S108: and if the wearing part is not consistent with the preset standard wearing part, carrying out the operation of solving the inverse number on the ECG detection data, and generating and displaying a oscillogram corresponding to the ECG detection data after the operation of the inverse number.

For example, the wearable device is an electrocardiographic watch, and the ECG detection data is calculated by subtracting the positive electrical signal from the negative electrical signal. The preset standard wearing part is worn by a left hand, and when the left hand is worn, the left hand is in contact with the anode, and the right hand is in contact with the cathode. The ECG detection data for the standard waveform is the electrical signal detected on the left hand minus the electrical signal detected on the right hand. If the wearing part determined according to the motion sensor and the ECG detection data is worn by the right hand, namely the right hand contacts the anode, and the left hand contacts the cathode, the electrical signal of the anode minus the electrical signal of the cathode is the electrical signal detected on the right hand minus the electrical signal detected on the left hand, namely the obtained ECG detection data is not the ECG detection data corresponding to the standard waveform, the ECG detection data needs to be subjected to an inversion operation, the ECG detection data after the inversion operation is the electrical signal detected on the left hand minus the electrical signal detected on the right hand, and a waveform diagram is generated and displayed according to the ECG detection data after the inversion operation. For example, if fig. 5 is a waveform diagram corresponding to EVG detection data, and if the wearing manner calculated from the waveform diagram of fig. 5 does not match a preset standard wearing manner, a waveform diagram is generated from ECG detection data after inverse number calculation, that is, the waveform diagram of fig. 5 is subjected to operations of keeping the abscissa unchanged and taking the ordinate as an inverse number to obtain a standard waveform diagram, so that the standard waveform diagram is convenient for the user to view.

S109: and if the first wearing information is inconsistent with the second wearing information, determining the wearing part according to third wearing information input by the user.

Specifically, if the first wearing information and the second wearing information are not consistent, it is indicated that the detection result is not accurate, the user needs to input the third wearing information again to determine the wearing part, and the display mode is determined according to whether the wearing part is consistent with the standard wearing part. For example, as shown in fig. 6, if the wearing part corresponding to the second wearing information is left-handed wearing, the current wearing part is displayed as left-handed wearing, and the user is prompted whether to change the wearing part. If the user selects yes, the display is carried out according to the display mode corresponding to the wearing part worn by the left hand, and if the user selects no, the display is carried out according to the display mode corresponding to the wearing part worn by the right hand. For example, if the standard wearing portion is left-handed, if the user selects yes, a waveform map corresponding to the ECG detection data is generated and displayed, and if the user selects no, an inversion operation is performed on the ECG detection data, and a waveform map corresponding to the ECG detection data after the inversion operation is generated and displayed.

S110: and if the first wearing information does not accord with the preset credible condition, determining a wearing part according to third wearing information input by the user.

Specifically, if the first wearing information does not meet the preset trusted condition, third wearing information input by the user is acquired, and the method for determining the wearing part according to the third wearing information is the same as that in step S109.

In the embodiment, the wearing position is determined according to the ECG detection data and the first wearing information, and the display mode is determined according to the fact that whether the wearing position is consistent with the preset standard wearing position or not, so that a standard oscillogram can be displayed at any wearing position, and a user can conveniently check the standard oscillogram.

As shown in fig. 7, the ECG detection method according to the second embodiment of the present application includes:

s201: and acquiring fourth wearing information input by the user.

The fourth wearing information is wearing position information, and for the electrocardiograph watch, the wearing position information includes left-hand wearing and right-hand wearing. For example, as shown in fig. 8, before the user uses the electrocardiographic watch, the user selects a wearing portion on the display interface.

S202: ECG detection data and first wearing information are acquired.

S203: second wearing information is calculated from the ECG detection data.

S204: and judging whether the first wearing information meets a preset credible condition.

S205: and if the first wearing information accords with the preset credible condition, judging whether the first wearing information and the second wearing information are consistent.

S206: and if the first wearing information is consistent with the second wearing information, determining the wearing part according to the consistent detection result.

S202 to S206 are the same as S101 to S105 in the first embodiment, and are not described herein again.

S207: and judging whether the wearing part determined according to the consistent detection result is consistent with the wearing part corresponding to the fourth wearing information.

S208: and if the wearing part determined according to the consistent detection result is consistent with the fourth wearing information, generating and displaying a oscillogram corresponding to the ECG detection data.

Specifically, after the fourth wearing information input by the user is acquired, the processor adjusts the calculation method of the ECG detection data according to the fourth wearing information, for example, for an electrocardiograph watch, if the calculation method of the ECG detection data corresponding to the standard form is to subtract the electrical signal detected on the left hand from the electrical signal detected on the right hand. The positive pole of the electrocardio-watch is arranged on the bottom cover of the electrocardio-watch, and the negative pole is arranged on the crown of the electrocardio-watch. If the wearing part corresponding to the fourth wearing information is worn by the left hand, namely the left hand is in contact with the positive electrode, and the right hand is in contact with the negative electrode, the processor sets the calculation method of the ECG detection data to be that the positive electrode electric signal is subtracted from the negative electrode electric signal. If the wearing part corresponding to the fourth wearing information is worn by the right hand, namely the right hand is in contact with the positive electrode, and the left hand is in contact with the negative electrode, the processor sets the calculation method of the ECG detection data to be that the negative electrode electric signal is subtracted from the positive electrode electric signal. And if the wearing part determined according to the first wearing information and the second wearing information is consistent with the wearing part corresponding to the fourth wearing information input by the user, indicating that the user setting is correct, and generating and displaying a oscillogram corresponding to the ECG detection data.

S209: and if the wearing part is not consistent with the wearing part corresponding to the fourth wearing information, performing an operation of obtaining an inverse number on the ECG detection data, and generating and displaying a oscillogram corresponding to the ECG detection data after the operation of the inverse number.

Specifically, since the wearing position is determined according to the coincidence detection result of the first wearing information and the second wearing information and is an authentic detection result, if the wearing position does not coincide with the wearing position corresponding to the fourth wearing information, it is indicated that the user has set an error, and if the calculation method of the ECG detection data set according to the fourth wearing information is incorrect, the ECG detection data is subjected to an operation of inverting the number, a waveform diagram corresponding to the ECG detection data after the operation of the inverting number is generated and displayed, and the fourth wearing information is modified at the same time, and the modified prompt information of the fourth wearing information is output.

S210: and if the first wearing information is inconsistent with the second wearing information, judging whether the second wearing information is consistent with the fourth wearing information.

Specifically, if the first wearing information and the second wearing information are not consistent, it is indicated that the detection result may be incorrect, and the wearing part is further determined according to fourth wearing information set by the user.

S211: and if the second wearing information is consistent with the fourth wearing information, generating and displaying a oscillogram corresponding to the ECG detection data.

Specifically, if the second wearing information matches the fourth wearing information, it is indicated that the user setting is correct, and a waveform diagram corresponding to the ECG detection data is generated and displayed.

S212: and if the second wearing information is inconsistent with the fourth wearing information, determining a wearing part according to fifth wearing information input by the user.

Specifically, if the second wearing information is not consistent with the fourth wearing information, the wearing part needs to be further determined according to fifth wearing information input by the user. For example, the wearing part corresponding to the fourth wearing information is displayed to prompt the user whether to change.

S213: if the first wearing information does not accord with the preset credible condition, judging whether the second wearing information is consistent with the fourth wearing information, and executing S211 or S212 according to whether the second wearing information is consistent with the fourth wearing information.

In the embodiment, the wearing part is determined according to the ECG detection data and the first wearing information, and the display mode is determined according to whether the wearing part is consistent with the wearing part corresponding to the pre-input fourth wearing information, so that the error information can be identified and the standard oscillogram can be displayed under the condition that the user has set errors, and the user can conveniently check the situation.
