In order to maintain human life, it is necessary to pass the blood released by the beating of the heart along the arteries all over the body without blockage, and to receive blood back to the heart through veins. Thus, oxygen and nutrients can be supplied to each tissue of the body and waste products consumed through metabolism can be removed.

However, if the blood is not properly delivered to a specific part of the body due to poor heart conditions, or if blood clots or embolisms occur in the blood and the blood becomes turbid, the capillaries of certain tissues of the body are blocked, causing tissue necrosis, which can endanger life. have. Therefore, in order to check the presence or absence of heart abnormalities, clinical examinations and imaging tests are used. As a method of early diagnosis, the ECG signal measured by measuring the ECG is displayed in the form of a graph to determine the presence or absence of an abnormality in the patient's heart. The method of judging is also widely used.

As for terms used in the embodiments, general terms that are currently widely used as possible are selected while taking functions of the present invention into consideration, but this may vary according to the intention or precedent of a technician working in the field, the emergence of new technologies, and the like. In addition, in certain cases, there are terms arbitrarily selected by the applicant, and in this case, the meaning of the terms will be described in detail in the description of the corresponding invention. Therefore, the terms used in the present invention should be defined based on the meaning of the term and the overall contents of the present invention, not a simple name of the term.

When a part of the specification is said to "include" a certain component, it means that other components may be further included rather than excluding other components unless specifically stated to the contrary. In addition, terms such as "... unit" and "... module" described in the specification mean a unit that processes at least one function or operation, which is implemented as hardware or software, or as a combination of hardware and software. Can be.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those of ordinary skill in the art may easily implement the present invention. However, the present invention may be implemented in various different forms and is not limited to the embodiments described herein.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the drawings.

Atrial fibrillation is one of the most common arrhythmia clinically, and its overall prevalence ranges from 0.4 to 0.9%. It increases by 0.1% to 0.2% each year from the age of 40 and beyond, and increases to 2 to 4% at the age of 60 or older. When atrial fibrillation is accompanied, atrial-ventricular synchronicity is lost and ventricular diastole is shortened, leading to shortness of breath and heart failure. In addition, in patients with atrial fibrillation, blood clots are formed in the atrium, causing systemic embolism such as cerebral infarction, which increases mortality. The increase in the occurrence of atrial fibrillation along with the increase in the elderly population can be said to have an important health and sociological significance in this respect. Since paroxysmal atrial fibrillation can develop into chronic atrial fibrillation, it is important to predict and diagnose the risk of paroxysmal atrial fibrillation.

Among the ECG signal components, the P-wave component is used as important information for prediction and diagnosis of such atrial fibrillation. Therefore, it is very important to develop an ECG signal in which the P wave component is well expressed in an electrocardiogram measuring device.

In particular, recently large hospitals use expensive ultrasound medical devices to accurately monitor the heart condition, and through this, the utilization of ECG measuring devices is gradually decreasing. However, the P-wave component cannot be measured even through ultrasonic medical devices installed in large hospitals.

According to embodiments of the present invention, in the process of generating an input analog ECG signal, the P wave component among the ECG signal components may be further enhanced. By applying different compensation values to the signal of the PR interval and the signal of the remaining interval, the P-wave component can be enhanced.

According to embodiments of the present invention, the signal gain is an element for adjusting the size of an ECG signal in a process of converting an analog input ECG signal component into a digital ECG signal component. For example, the compensation value of the PR section may be applied as a relatively high value, and the compensation value of the remaining section may be applied as a relatively low value. As the compensation value of the P-wave section is larger than the compensation value of the remaining section, the size of the P-wave component may be increased. Here, the analog compensation value is used for convenience of explanation, but it is natural that the compensation value (precision) of the signal may be changed while converting the analog signal into a digital signal, or the digital signal may be processed by a processor. In addition, although the compensation value is used for convenience of explanation, it is natural that the digital signal can be processed through nonlinear mapping.

In an embodiment of the present invention, if the compensation value is set to be constant over the entire ECG signal period, a problem may occur that the signal quality for various noises such as body noise and movement noise is deteriorated.

1A is a diagram illustrating a network environment of an electrocardiogram measuring apparatus according to embodiments of the present invention.

As shown in FIG. 1A, the electrocardiogram measuring device is a device that is non-invasively or invasively mounted on an object obj to sense an electrocardiogram according to the heartbeat of the object. Here, the object obj may be a part of a human or animal body, such as a person, an animal, or a chest, but is not limited thereto. It is assumed that any object can be an object as long as it can sense or measure an electrocardiogram. In addition, an electrocardiogram is a graph that records the change in potential on the body surface according to the mechanical activity of the heartbeat, such as contraction/expansion of the heart muscle. It is the same as the meaning of'sensing an electric potential' occurring on the surface. The electrocardiogram measuring apparatus may transmit and receive data to and from a user terminal using a communication module. The communication module may include various communication modules such as a wireless Internet module, a short-range communication module, and a mobile communication module.

The wireless Internet module is an external network according to communication protocols such as Wireless LAN (WLAN), Wi-Fi, Wireless broadband (Wibro), World Interoperability for Microwave Access (Wimax), and High Speed Downlink Packet Access (HSDPA). It means a module that is connected to and performs communication.

The short-range communication module is based on a short-range communication method such as Bluetooth, Radio Frequency Identification (RFID), infrared data association (IrDA), Ultra Wideband (UWB), and ZigBee. It means a module for performing communication.

The mobile communication module refers to a module for performing communication by accessing a mobile communication network according to various mobile communication standards such as 3rd Generation (3G), 3rd Generation Partnership Project (3GPP), and Long Term Evolution (LTE).

However, the present invention is not limited thereto, and if it is capable of transmitting and receiving various signals and data while performing communication with the electrocardiogram measuring apparatus 100, the communication unit 120 may employ other types of communication modules in addition to those described above.

The electrocardiogram measuring apparatus 100 may further include a band-type mounting portion. It may be made of a flexible material that can be deformed according to the curved surface of the body surface, for example, elastic, that is, elastic fabric. The mounting portion may be provided in a patch type or a wearable type. It is only necessary to be able to sense the electric potential generated on the body surface by contacting the body surface of the object by wearing through the mounting part.

As shown in FIG. 1B, the electrocardiogram measuring apparatus 100 may include a button 11. The electrocardiogram measuring apparatus 100 may input a predetermined on/off through the button 11. The electrocardiogram measuring device 100 forms an exterior covered with the cases 21 and 22. The cases 21 and 22 form the exterior of the electrocardiogram measuring apparatus 100 and perform a function of accommodating and protecting various components in a space formed therein.

The cases 21 and 22 may be made of a plastic material that does not transfer heat well or a metal material coated with a heat shielding material on the surface. The cases 21 and 22 may be manufactured by, for example, an injection molding method, a 3D printing method, or a method of assembling small parts manufactured by injection molding.

In the electrocardiogram measuring apparatus 100 according to the embodiment shown in FIGS. 1B and 1C, the cases 21 and 22 are not essential components, and the cases 21 and 22 may not be installed if necessary.

A button 11 that receives input from a user may be disposed on the upper surface of the case 21.

As illustrated in FIG. 1C, when the case 21 of the electrocardiogram measuring apparatus 100 is removed, the battery 23 and the button 12 supplying power are exposed. When the case 21 is removed, it corresponds to the signal detection unit 110, the signal conversion unit 120, the processor 130, the sensor unit 140, the memory 160, and the communication unit 170 for the operation of the electrocardiogram measurement device. Elements can be exposed.

2 is a block diagram of an electrocardiogram measuring apparatus according to embodiments of the present invention.

As shown in FIG. 2, the electrocardiogram measuring apparatus includes a signal detection unit 110, a signal conversion unit 120, a processor 130, a sensor unit 140, and a power supply unit in order to detect an electrical signal generated from the heart of an object. 150), a memory 160, and a communication unit 170 may be included.

The signal detector 110 outputs an electrocardiogram analog signal by detecting an electrical signal from the heart of the object.

The signal converter 120 may convert an electrocardiogram analog signal into an electrocardiogram digital signal. The processor 130 receives an electrocardiogram digital signal and writes it to a memory. The processor 130 analyzes the components of the electrocardiogram digital signal or the electrocardiogram analog signal, detects a specific component, for example, a P wave component, detects a first section corresponding to the specific component, and detects the first section of the ECG digital signal and the first section. Different compensation values may be applied to the electrocardiogram digital signal of the second period except for the first period, and an electrocardiogram digital signal to which the compensation value was applied may be generated and recorded in the memory. The processor 130 may transmit an electrocardiogram digital signal to an external device.

The processor 130 may detect a specific component in the electrocardiogram digital signal by using the magnitude and slope of the signal. The average size or average slope of the specific component may be detected based on the collected data on the specific components, and the specific component may be detected through the collected data on the P wave components.

In another embodiment, the processor 130 may detect a specific component by comparing the electrocardiogram digital signal with a template of a standard electrocardiogram waveform.

In another embodiment, the processor 130 may detect a peak component in an electrocardiogram analog signal or an electrocardiogram digital signal using a signal amplitude and a slope, and then detect a P wave component by using the peak component. Here, the peak component may refer to a component including a point in the electrocardiogram signal with the largest signal amplitude. The processor 130 may detect, as a P-wave component, a component that is closest to the peak component and has a non-zero signal amplitude.

With regard to detecting the peak component, the processor 130 is a time point at which the slope value of the electrocardiogram analog signal or the electrocardiogram digital signal changes from a positive value to a negative value, that is, a time point when the slope value of the signal is 0 or the slope value of the signal is infinite. The point of time at which the size of is at the maximum value can be detected as a peak component. The processor 130 may detect, as a specific component, a section in which the magnitude of the signal is within a preset range in the section before the peak component. The processor 120 may detect, as a specific component, a section closest to the section prior to the peak component and in which the signal has a non-zero magnitude. The processor 130 may detect, as the P wave component, a section closest to the section before the peak component, in which the shape of the ECG signal is similar to the preset pattern. Here, the electrocardiogram signal may be an electrocardiogram analog signal or an electrocardiogram digital signal.

The processor 130 applies a first compensation value to the electrocardiogram digital signal of the first section including a specific component, and applies a second compensation value to the electrocardiogram digital signal of the rest period except for the first section. Measurement data can be generated. In this case, the second compensation value may be a value smaller than the first compensation value. That is, by applying a compensation value larger than that of the remaining sections to a specific component, detection, display, and recognition of a specific component can be enhanced.

The processor 130 may set a section in which the slope value or the absolute value of the slope value is less than or equal to a preset value in the section before the peak component and the signal magnitude is not 0 as a section including a specific component.

The processor 130 detects a peak component, determines a first section including a P wave component based on the detected peak component, and determines a first section and a second section other than the first section. The processor 130 may apply different compensation values to the first section and the second section, respectively.

The processor 130 may detect a peak component including a point where the signal has a maximum value, and set a section including a specific component based on the section including the peak component. The processor 130 may set a set of points adjacent to the peak component and having a non-zero slope as a section including the peak component.

Before applying the compensation value, the processor 130 may increase the size of the electrocardiogram digital signal by applying an initial compensation value to the components of the electrocardiogram digital signal.

As methods of applying the compensation value, the process 130 may control a conversion gain value of the signal conversion unit. It is natural that the process 130 may control the signal detection unit 110 or control itself in the process 130.

The processor 130 may reduce the amount of total data by applying a compensation value to a section including the P wave component and applying a compensation value of 0 to a section other than the section including the P wave component.

In addition, the processor 130 may record a compensation value or a compensation control signal in the memory together with the electrocardiogram digital signal to which the compensation value is applied. The processor 130 may transmit the compensation value or the compensation control signal together with the ECG signal to which the compensation value is applied to a user terminal or an external storage device through a wired or wireless communication method (eg, through a local area network).

The processor 130 generates measurement data based on the electrocardiogram digital signal, and records the measurement data in a memory. When an abnormal event is detected from the electrocardiogram digital signal, the processor 130 detects a section of measurement data corresponding to the detected time point, inserts a tag related to the event in connection with the section of the measurement data, and stores the measurement data in which the tag is inserted. It can be transmitted to an external user terminal.

Here, the abnormal event refers to an event such as a risk sign or an abnormal sign for the heart, and may be detected through an electrocardiogram digital signal or set through an input through an input unit. The tag related to the event may be generated in consideration of the abnormal event acquired through the sensor unit and context data related to the abnormal event. The tag related to the event may be generated including information on pain related to the heart based on context data detected at the time when the abnormal event is detected. The tag related to the event may be generated based on data input through an input unit included in the electrocardiogram measuring apparatus 100. Tags related to the event may include input voice data, text data, image data, and the like. The tag related to the event can also be set through the on/off button.

In another embodiment, the tag related to the event may be generated, including information on pain and discomfort related to the heart, based on context data sensed at the sensed time point. The processor 130 may further collect context data in relation to the abnormal event. The processor 130 may sense context data through a sensor unit or receive context data through a user terminal. The context data may include a change in movement of a user adjacent to a detection time point of an abnormal event, an input value through an input unit, input data input through a user terminal, and the like.

The processor 130 may separately generate sections including the abnormal event as data. The processor 130 may separately generate tag measurement data obtained by searching for sections in which tags are inserted and collecting data on sections in which tags are inserted. The processor 130 may transmit the tag measurement data to a preset administrator's user terminal. In this case, the administrator refers to a user who has a predetermined medical-related authority (diagnosis, treatment, etc.), and may be set in association with the object to be measured.

The processor 130 may further insert a message received from the user terminal into the measurement data into which the tag is inserted. In addition, it is natural that the compensation value may be different when such a tag is inserted.

The sensor unit 140 senses motion to be detected. The sensor unit 140 may sense the motion by detecting the motion in the X, y, and z axis directions.

The power supply unit 150 supplies power to the signal detection unit 110, the signal conversion unit 120, the memory 160, the processor 130, and the like. The power supply unit 150 may be a lithium iron phosphate (LiFePO4) battery, but is not limited thereto, and may be manufactured as a lithium cobalt oxide (LiCoO2) battery, a lithium titanate battery, or the like. The power supply unit 150 may be a rechargeable battery or a disposable battery.

The memory 160 may store data related to ECG measurement. The memory 16 may store information on an object, a measurement time, and measured ECG-related data. The memory 160 is hardware that stores various types of data processed in the electrocardiogram measuring apparatus 100, and the memory 160 may store data processed by the processor 130 and data to be processed. In particular, FIG. 6 An example of a compensation value to be applied and a compensation value for each step may be stored. The event generated in FIG. 8 and the event-related tag may be stored. The memory 160 includes a variety of random access memory (RAM) such as dynamic random access memory (DRAM), static random access memory (SRAM), read-only memory (ROM), and electrically erasable programmable read-only memory (EEPROM). It can be implemented in types.

The communication unit 170 may receive a control signal from an external electronic device. The communication unit 170 may transmit measured data to an external electronic device.

6 is a flowchart of a method of measuring an electrocardiogram according to embodiments of the present invention.

As shown in FIG. 6, the electrocardiogram measuring apparatus 100 may output an electrocardiogram analog signal by detecting an electrical signal from the heart of the object (S110).

The electrocardiogram measuring apparatus 100 may convert an electrocardiogram analog signal into an electrocardiogram digital signal (S120).

The electrocardiogram measuring apparatus 100 may detect a P wave component by analyzing a component of the electrocardiogram digital signal (S130).

The electrocardiogram measuring apparatus 100 may detect a P-wave component from the electrocardiogram digital signal by using the magnitude and slope of the signal. The average size or average slope of the P-wave components may be detected based on the collected data on the P-wave components, and the P-wave components may be detected through the collected data on the P-wave components.

In another embodiment, the electrocardiogram measuring apparatus 100 may detect a P wave component by comparing the electrocardiogram digital signal with a template of a standard electrocardiogram waveform.

In another embodiment, the electrocardiogram measuring apparatus 100 may detect a peak component in an electrocardiogram digital signal using a signal amplitude and a slope, and then detect a P wave component using the peak component. The electrocardiogram measuring apparatus 100 may detect, as a P-wave component, a component that is closest to and has a non-zero signal magnitude among arbitrary sections prior to the peak component.

In connection with detecting the peak component, the electrocardiogram measuring apparatus 100 may detect a time point at which the slope of a signal changes from a positive value to a negative value, a time point at which the signal magnitude reaches a maximum value, and the like as the peak component. The electrocardiogram measuring apparatus 100 may detect a section in which the signal amplitude is within a preset range in the section before the peak component as a P wave component. The electrocardiogram measuring apparatus 100 may detect a section closest to the section before the peak component, in which the signal amplitude is not 0, as the P wave component. The electrocardiogram measuring apparatus 100 may detect, as a P wave component, a section closest to the section before the peak component, in which the shape of the ECG signal is similar to a preset pattern. Here, the electrocardiogram signal may be an electrocardiogram digital signal or an electrocardiogram analog signal.

The electrocardiogram measuring apparatus 100 applies a first compensation value to the electrocardiogram signal of the first section including the P wave component, and applies the second compensation value to the electrocardiogram signal of the rest period except the first section. You can generate measurement data for In this case, the second compensation value may be a value smaller than the first compensation value. That is, by applying a compensation value larger than that of the remaining sections to the P wave component, detection, display, and recognition of the P wave component can be enhanced.

At this time, the first compensation value applied to the P wave component may increase or decrease over several steps. If the size of the P wave component does not satisfy a predetermined condition after applying the first compensation value, the first compensation value may be adjusted to a different value. For example, after applying the first compensation value, when the size of the P wave component is less than or equal to the minimum size value, the first compensation value may be adjusted to a value larger than the previous compensation value. In addition, when the size of the P wave component is greater than or equal to the maximum value after applying the first compensation value, the first compensation value may be adjusted to a value smaller than the previous compensation value. The range of adjustment of the compensation value may be determined according to a preset ratio.

The electrocardiogram measuring apparatus 100 may set a section including a P wave component in a section before the peak component in which the slope value or the absolute value of the slope value is less than or equal to a preset value and the signal magnitude is not 0.

The electrocardiogram measuring apparatus 100 may apply different compensation values to the first section including the P-wave component and the second section, which is the remaining section excluding the first section (S140).

The processor 130 of the electrocardiogram measuring apparatus 100 may record the applied compensation values together with measurement data for the electrocardiogram in a memory or transfer the applied compensation values to an external device. A separate table including applied compensation values may be created.

The electrocardiogram measuring apparatus 100 may record an electrocardiogram digital signal to which different compensation values are applied to a memory or transmit it to an external device (S150).

7 is an exemplary diagram related to setting of a first section and a second section.

The electrocardiogram measuring apparatus 100 may set the section including the P wave component as an arbitrary section preceding the peak component. In the section preceding the peak component, the P wave component can be detected based on the magnitude and slope of the signal. The electrocardiogram measuring apparatus 100 may set the first periods S1 and S3 including a period in which the amplitude of a signal existing adjacent to the P wave component is 0. The electrocardiogram measuring apparatus 100 may set a first section S2 including a section in which the magnitude of an adjacent signal is 0 prior to the P wave component.

The tag related to the event may be generated based on data input through an input unit included in the electrocardiogram measuring apparatus 100. Tags related to the event may include input voice data, text data, image data, and the like. The tag related to the event can also be set through the on/off button.

In another embodiment, the tag related to the event may be generated, including information on pain and discomfort related to the heart, based on context data sensed at the sensed time point. The electrocardiogram measuring apparatus 100 may further collect context data in relation to the abnormal event. The electrocardiogram measuring apparatus 100 may sense context data through a sensor unit or receive context data through a user terminal. The context data may include a change in movement of a user adjacent to a detection time point of an abnormal event, an input value through an input unit, input data input through a user terminal, and the like.

The electrocardiogram measuring apparatus 100 transmits the measurement data in which the tag related to the event is inserted to the user terminal (S240).
