Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be understood that the terms "comprises" and "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.
The technical schemes described in the embodiments of the present invention may be arbitrarily combined without any collision.
In addition, in the embodiments of the present invention, "first", "second", etc. are used to distinguish similar objects and are not necessarily used to describe a particular order or precedence.
The electrocardiographic exercise load test is a method for increasing the heart load through a certain amount of exercise and observing the change of the electrocardiogram, is considered as an important cardiovascular examination means because of being simple, practical, low in cost, atraumatic, accordant with physiological conditions and relatively safe, and is also applied to clinical evaluation of cardiovascular diseases, especially coronary atherosclerotic heart diseases (coronary heart diseases).
In the electrocardiographic exercise stress test, the related art generally measures an electrocardiogram by a user running on a treadmill while standing up on the upper body. In the process of measuring an electrocardiogram, the upper body of a user can shake due to running of the user, so that the measured electrocardiogram contains more interference signals, the waveforms which can be referred to in the electrocardiogram are not more, and the doctor is blocked from acquiring information from the electrocardiogram. Moreover, the electrocardiogram of the upright upper body obtained by the electrocardiogram exercise load test in the related art has low contrast with the resting electrocardiogram obtained by lying down, and affects the diagnosis result of doctors.
In view of the above-mentioned drawbacks of the related art, an embodiment of the present invention provides an electrocardiogram measurement method capable of avoiding interference signals caused by upper body shake of a user. In order to illustrate the technical scheme of the invention, the following description is made by specific examples.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an electrocardiogram measuring system according to an embodiment of the present invention, the system includes: electronic equipment, electrocardiographic measurement equipment, and a bicycle. The electronic device, the electrocardiographic measurement device and the bike may be connected to each other by wireless communication.
First, a user wears an electrocardiogram measuring apparatus for measuring electrocardiogram data of the user on the upper body of the user. And then the user performs an electrocardiogram exercise load test by riding the bicycle in a prone position. And the electrocardiogram measuring equipment transmits the measured electrocardiographic data to the electronic equipment, and the electronic equipment adjusts the resistance of the bicycle in real time according to the acquisition parameters of the electrocardiographic data. Here, the bicycle can control the riding resistance by controlling the tightness between the wheel and the brake pad, and the greater the riding resistance, the more effort the user needs to use to step on the pedal of the bicycle.
The electronic device may be a mobile phone, a tablet computer, a desktop computer, etc. The electronic device may also be a medical special-purpose computer in which only medical software is installed in a hospital.
The electrocardiograph measuring equipment can be intelligent electrocardiograph underwear or intelligent electrocardiograph vest, wherein an electrocardiograph sensor is arranged in the electrocardiograph measuring equipment, and the electrocardiograph sensor collects 12-lead electrocardiograph signals. The electrocardiograph measuring device can also be a traditional electrocardiograph monitor, a 15-conductive electrocardiograph monitoring device or an 18-conductive electrocardiograph monitoring device.
Fig. 2 shows an example of an implementation of a bicycle, as shown in fig. 2, in which a shoulder strap and a waist strap are provided on a seat of the bicycle for securing the upper body of the user while the user lies flat on the seat of the bicycle, reducing the shake of the upper body of the user while riding the bicycle. The left side and the right side of the bicycle can be respectively provided with a hand holding handle for fixing the hands of a user, and the bicycle is convenient for the user to exert force while further fixing the upper body.
Based on the above-mentioned electrocardiogram measuring system, fig. 3 is a schematic flow chart of an implementation of an electrocardiogram measuring method according to an embodiment of the present invention, where an execution body of the method is the electronic device shown in fig. 1. Referring to fig. 3, the electrocardiogram measuring method includes:
S101, collecting first electrocardiographic data of a user; the user maintains riding movement through the bicycle in a prone position when the first electrocardiographic data is acquired.
In the embodiment of the invention, the user wears the electrocardiogram measuring equipment and keeps riding movement through the bicycle in the prone position state, and the electrocardiogram measuring equipment transmits the measured electrocardiogram data to the electronic equipment in real time.
When the first electrocardiographic data of the user is acquired, the method further comprises:
s1011, determining the acquisition parameters of the first electrocardiographic data in real time.
The electronic equipment receives the first electrocardiograph data measured by the electrocardiograph measuring equipment in real time and determines real-time acquisition parameters of the first electrocardiograph data. In an embodiment of the present invention, the first electrocardiographic data real-time acquisition parameters include: heart rate values.
In practical applications, since the electrocardiographic signals acquired by the electrocardiographic measurement device may have noise due to interference of various external or internal factors (for example, respiration of the user), filtering processing is required for the acquired electrocardiographic data. In practical applications, the electronic device may use a digital filter to reject noise after receiving the first electrocardiographic data measured by the electrocardiographic measurement device. For another example, the electrocardiogram measuring device includes a digital filter, and the electrocardiogram measuring device filters noise in the electrocardiogram data and then transmits the electrocardiogram data to the electronic device. For example, a digital filter may be used to eliminate 50Hz/60Hz power frequency noise in electrocardiographic data; the myoelectric interference in the electrocardiographic data can be filtered out in a wavelet decomposition mode, wherein the myoelectric interference refers to interference generated by muscle tension and force of a user; and the electrocardiograph data can be filtered by a median filtering method to eliminate respiratory interference. After the electrocardio data are processed, interference noise in the electrocardio data can be filtered.
S1012, adjusting the riding resistance of the bicycle according to the acquisition parameters.
In one embodiment, as shown in fig. 4, the adjusting the riding resistance of the bicycle according to the acquisition parameters includes:
s201, when the heart rate value does not reach the first set value, increasing the riding resistance of the second set value at intervals of the set time.
In the embodiment of the invention, the electronic equipment increases the riding resistance of the second set value of the bicycle at set time intervals. For example, the electronic device can control the riding resistance of the bicycle by controlling the tightness between the wheel and the brake pad, if the tightness between the wheel and the brake pad is classified into 0 to 10 classes, 0 is no contact between the wheel and the brake pad, and 10 is the wheel cannot rotate. The level of tightness between the wheel and the brake pad can be increased by 1 every 1 minute, thus realizing a continuous increase of the riding resistance of the bicycle according to the set time interval.
In practical applications, the first setting may be set according to a maximum heart rate value of the user, which is equal to 220 minus the age of the user. For example, the first setting may be initially set to a 50% maximum heart rate value, if the user is 40 years old, the maximum heart rate value is 180BPM, and the first setting is 90BPM. The riding resistance of the bicycle is increased at set time intervals until the user heart rate value does not reach 90BPM.
S202, stopping increasing the riding resistance of the bicycle when the heart rate value reaches a first set value.
When the heart rate value of the user reaches the first set value, the riding resistance of the bicycle is stopped to be increased, the current riding resistance is kept unchanged, and the safety accidents caused by overlarge riding resistance after myocardial ischemia of the user can be avoided.
S203, judging whether a signal for confirming to stop riding is received within a set time length.
Judging whether the electronic equipment receives a signal for confirming stopping riding in a set time length when a user rides the pedal with the current riding resistance, wherein the set time length can be 3 minutes.
The signal confirming the stopping of riding is triggered by the doctor operating on the electronic device, for example, the doctor can trigger the signal confirming the stopping of riding through an input panel arranged on the surface of the electronic device, and the input panel can be a mechanical key panel or a touch display screen. In practical application, when carrying out an electrocardiogram exercise load test, a doctor is usually required to monitor the electrocardiogram of the user at the user side, and the doctor observes the electrocardiogram of the user at any time, so that the user immediately stops riding the bicycle when myocardial ischemia occurs to ensure the life safety of the user. Meanwhile, the doctor triggers a signal for confirming the stopping of riding on the electronic equipment, and after the electronic equipment triggers the signal for confirming the stopping of riding, the electronic equipment stops receiving the electrocardiographic data and controlling the riding resistance of the bicycle.
After stopping the exercise stress test, the heart rate is maintained for a while and then slowly decreases. Therefore, after the user stops riding, the electronic device can continuously receive electrocardiographic data for a period of time, a doctor observes electrocardiographic waveforms for the period of time, judges whether the user does not have myocardial ischemia, and if the user does not have myocardial ischemia, the exercise load test can be continuously carried out.
S204, if the signal is not received within the set time, adding a preset value to the first set value, wherein the first set value is smaller than or equal to the maximum heart rate value.
If the signal confirming stopping riding is not received within the set time, the electronic equipment increases the preset value to the first set value, and the electronic equipment increases the riding resistance of the bicycle at intervals of set time.
In an embodiment of the present invention, adding a preset value to the first set value includes:
multiplying the maximum heart rate value of the user by a set percentage to obtain the preset value;
and adding a preset value to the first set value.
For example, the preset value=10% maximum heart rate value, and the second set value=the first set value+10% maximum heart rate value, where the second set value is the first set value after the preset value is increased.
If the electronic equipment receives a signal for confirming stopping riding in a set time period, the electronic equipment stops receiving the electrocardiographic data, wherein the signal indicates that the electrocardiographic exercise load test is finished.
According to the embodiment of the invention, by collecting the first electrocardiographic data of the user in the prone position state, under the condition that the heart rate value reaches the first set value, the increase of the riding resistance of the bicycle is stopped, and the life safety of the user can be prevented from being threatened due to overlarge riding resistance after myocardial ischemia of the user occurs. Compared with the prior art, the method and the device continuously increase the rotating speed of the running machine, the riding resistance of the bicycle is adjusted through the heart rate value of the user, so that safety accidents of the user in the electrocardiogram measuring process can be avoided, the electrocardiogram of the user can be measured more safely, and the measured electrocardiogram is more referential.
In one embodiment, referring to fig. 5, the electrocardiogram measurement method further includes:
s301, receiving second electrocardiographic data of a user; the second electrocardiograph data is collected and sent by the electrocardiograph measuring equipment; the user maintains a resting state in a prone position when the electrocardiogram measuring device collects the second electrocardiogram data.
And the user keeps a resting state in the prone position state, second electrocardiograph data of the user are collected through the electrocardiograph measuring equipment, and the second electrocardiograph data are sent to the electronic equipment.
Preferably, the acquisition of the second electrocardiographic data should be performed before the acquisition of the first electrocardiographic data, i.e. after the acquisition of the second electrocardiographic data is completed, followed by the acquisition of the first electrocardiographic data. Here, the same gesture is used, and the first electrocardiographic data and the second electrocardiographic data are continuously acquired in the close time, the body position of the user is unchanged in the acquisition process, and the position of the electrocardiographic electrode is unchanged, so that the correspondingly output first electrocardiograph and the second electrocardiograph have higher relevance, and more reliable information can be conveniently analyzed from the first electrocardiograph and the second electrocardiograph.
In addition, the electronic equipment measures the first electrocardiogram of the user immediately after measuring the second electrocardiogram of the user, and the posture does not need to be replaced, so that the measurement time can be saved, and the measurement efficiency can be improved.
S302, outputting a first electrocardiogram according to the first electrocardiograph data; and outputting a second electrocardiogram according to the second electrocardiogram data on a display interface for outputting the first electrocardiogram.
The first electrocardiogram and the second electrocardiogram are output on the electronic equipment, and the first electrocardiogram and the second electrocardiogram are displayed simultaneously. For example, as shown in fig. 6, on the same electrocardiographic sheet, the upper half displays a first electrocardiogram, and the lower half displays a second electrocardiogram. In a normal electrocardiogram, the waveform of R waves is highest, and as can be seen from fig. 6, the abscissa is time, and in the same period, there are 4R waves in the electrocardiogram in the exercise state, and only 3R waves in the calm state. Since there is only one R wave in one time domain period, it can be seen that the time domain period of the electrocardiographic waveform in the motion state is shortened. As another example, as shown in fig. 7, the first electrocardiogram and the second electrocardiogram are simultaneously displayed on the same coordinate axis, and are distinguished using different colors. The first electrocardiogram and the second electrocardiogram are compared and displayed, so that a doctor can observe the change of the electrocardiogram conveniently, and useful information can be acquired from the electrocardiogram rapidly.
The outputting a second electrocardiogram according to the second electrocardiogram data at the display interface outputting the first electrocardiogram comprises the following steps:
transversely scaling the waveform of the second electrocardiogram, and outputting the waveform at the display interface; in the display interface, a peak of each R wave in the second electrocardiogram is aligned with a peak of each R wave in the first electrocardiogram.
In an electrocardiogram acquired by the user in a resting state, the waveform of each cycle may be considered to be the same, for example, the waveform of the R wave appearing in the first cycle is the same as the waveform of the R wave appearing in any one of the following cycles. In practical application, a waveform with a single heart beat period with better repeatability in the second electrocardiogram can be selected as a representative of the electrocardiogram waveform, and in one section of electrocardiogram waveform, if the waveform of each heart beat period is similar, the repeatability of the section of electrocardiogram waveform can be considered to be better, wherein any heart beat period can be called as the single heart beat period.
When the peaks of the R waves of the first electrocardiogram and the second electrocardiogram are aligned, the peaks of the first R wave and the peaks of the last R wave may be aligned according to the sequence of occurrence of the waveforms.
Specifically, the waveform between the first RR intervals in the second electrocardiogram is scaled, and the later waveform is temporarily unchanged, and the RR intervals are distances between the abscissas of the peaks of 2 continuous R waves. The waveform between the RR intervals is scaled on the time axis (horizontal axis) and the voltage amplitude (vertical axis) is unchanged, so that the two R wave peaks of the waveform are aligned with the two R wave peaks of the first RR interval in the first electrocardiogram, respectively. Thus, the first 2R wave peaks in the electrocardiogram are aligned, and then the rest R wave peaks are continuously aligned according to the method until the last R wave peak in the first electrocardiogram is aligned.
Because the doctor observes the electrocardiogram, mainly observes the waveform between 2 continuous R waves, through aligning each R wave crest in first electrocardiogram and the second electrocardiogram, can make things convenient for the doctor to see the change of the wave amplitude of each cycle in the electrocardiogram, be convenient for the doctor to acquire information from the electrocardiogram.
It will be appreciated that the R-wave position in the electrocardiogram needs to be located before the RR intervals are aligned, and that the R-wave waveform is highest in a normal electrocardiogram and most easily located in the electrocardiogram. However, in some cases, such as myocardial ischemia, the T-wave is higher than the R-wave, and therefore, the R-wave cannot be located by a simple judgment of the waveform height, and it is necessary to locate the position of the R-wave in the electrocardiogram by an algorithm. For example, in practical applications, the R-wave may be located by a filter method.
In practical applications, the waveform of the second electrocardiogram may be scaled using a fractional sample rate conversion method. From the nyquist sampling theorem, the original signal can be recovered without distortion as long as the sampling rate is greater than the nyquist frequency. The frequency spectrum range of the electrocardiosignal is generally lower than 50Hz, and the Nyquist sampling theorem is satisfied, so that the characteristic extraction process of the electrocardiosignal cannot be influenced when the sampling frequency of the electrocardiosignal is converted. First, B times of interpolation is carried out on the electrocardiosignal, and A times of extraction is carried out, so that a zoomed electrocardiogram can be obtained. Wherein the specific values of A and B are related to RR intervals of the first electrocardiogram and the second electrocardiogram. Compared with the common waveform scaling method, the waveform scaling method can keep more characteristic signals in the electrocardiosignal.
The electrocardiograph measurement method further includes:
determining a first waveform of which the ST segment meets a first setting condition in the first electrocardiogram, and determining a second waveform of which the ST segment does not meet the first setting condition;
rendering the first waveform in a first color; rendering the second waveform in a second color; wherein, the liquid crystal display device comprises a liquid crystal display device,
The first set of conditions characterizes the ST segment anomaly.
For example, in practical applications, a waveform showing ST segment abnormality in the first electrocardiogram may be displayed in red, and a waveform showing ST segment abnormality may be displayed in green. The abnormal waveform of the ST segment in the electrocardiogram is displayed by using the color different from other waveforms, so that a doctor can quickly find the abnormal waveform in the electrocardiogram, the time for the doctor to observe the electrocardiogram is saved, and the diagnosis speed of the doctor is increased.
In the first electrocardiogram, the electronic device can judge whether the first setting condition is satisfied by comparing the variation of the amplitude of the ST-segment waveform in the first electrocardiogram with the variation of the amplitude of the ST-segment waveform in the second electrocardiogram. For example, if the amplitude of the ST segment waveform in the first electrocardiogram is lower by 0.3mV or more or higher by 0.5mV or more than the amplitude of the ST segment waveform in the second electrocardiogram, the first set condition may be considered to be satisfied, indicating that the waveform of the ST segment is abnormal.
The electrocardiographic measurement method further includes, when receiving the first electrocardiographic data of the user:
monitoring the acquisition parameters;
early warning is carried out when the acquisition parameters are abnormal; wherein, the liquid crystal display device comprises a liquid crystal display device,
the acquisition parameters include at least one of: heart rate value, blood pressure and blood oxygen.
In the process of measuring the electrocardiographic data of the user, the acquisition parameters are monitored in real time, when the acquisition parameters are abnormal, the alarm is immediately given, a doctor is informed to rescue the user, and the life safety of the user is protected. In practical application, the armpit body temperature, the respiratory rate, the brain electrical signals and the like of the user can be measured. Through multiple signal monitoring, the electrocardiograph data of the user can be measured more safely, the probability of dangerous occurrence is reduced, the workload of doctors or nurses is reduced, and the working efficiency is improved.
Fig. 8 is a flow chart showing an implementation of an electrocardiogram measuring method provided by an application embodiment of the present invention, in which electrocardiogram measurement is used for performing a relevant examination of cardiovascular diseases. In patients with cardiovascular disease, although there is a coronary stenosis in the resting state, the myocardial demand for blood and oxygen does not exceed the supply, and the myocardium can still obtain a sufficient blood supply from the stenosed coronary artery, so that there is no ischemic change in the electrocardiogram in the resting state. Since the movement can increase the demand of coronary artery blood supply, the myocardial metabolism is obviously increased when the movement is performed, the coronary artery with lesion is not laid out, the relative blood supply of the myocardial is insufficient, the ischemic change can be reflected on the electrocardiogram, if the coronary artery has no lesion, the supply and demand balance can not be reflected on the electrocardiogram. Thus, cardiovascular disease of a patient can be examined by comparing electrocardiograms in a resting state and in a sports state. Referring to fig. 8, the electrocardiogram measuring method includes:
s401, setting a first set value.
For example, the first setting may be a 50% maximum heart rate value. The first set value varies from person to person according to the physical condition of the user, such as age, sex, etc.
S402, receiving electrocardiographic data when the user keeps a resting state in a prone position.
S403, receiving electrocardiographic data of a user in a prone position when the user keeps riding through the bicycle, and determining acquisition parameters of the electrocardiographic data, wherein the acquisition parameters comprise heart rate values.
After the electrocardiographic data of the user in the resting state are received, the user continues to perform the bicycle exercise in the prone position state, and electrocardiographic data of the user during exercise are collected.
S404, when the heart rate value does not reach the first set value, increasing the riding resistance of the second set value at intervals of the set time.
S405, stopping increasing the riding resistance of the bicycle when the heart rate value reaches a first set value.
S406, judging whether a signal for confirming to stop riding is received within a set time length.
If the signal is not received within the set time period, step S407 is executed; if the signal is received within the set period of time, step S408 is performed.
S407, adding a preset value to the first set value, wherein the first set value is smaller than or equal to the maximum heart rate value.
And S408, stopping receiving the electrocardiographic data.
S409, outputting a resting electrocardiogram and a sports electrocardiogram according to the electrocardiographic data.
The specific implementation process of the steps in the above embodiments is detailed in the method embodiments, and will not be repeated here.
By the electrocardiogram measuring method provided by the embodiment, the electrocardiogram data of the user are acquired in the prone position, interference noise caused by shaking of the upper body of the user can be avoided, and the exercise electrocardiogram and the resting electrocardiogram acquired in the same posture have contrast and reference value, so that a doctor can acquire useful information from the electrocardiogram conveniently.
