[0043] Reference Figure 1 , Figure 1 : is a structural diagram of a heart image display device provided by the present invention. The heart image display device provided by an embodiment of the present invention includes a memory and a processor, the memory is used to store a computer program, and the processor is used to execute the computer program to implement the following steps:

[0044] Receive the target user's ECG signal;

[0045] determining an electrocardiographic event or a cardiac state based on the electrocardiographic signal;

[0046] Based on the electrocardiographic event or the cardiac state, a cardiac image is generated and displayed.

[0047] It should be noted that the memory and the processor are connected wirelessly or wired, the wireless method includes but is not limited to Bluetooth and wireless LAN, and the wired method includes but is not limited to serial port connection. Therefore, the processor can call the computer program in the memory, that is, the computer executable code.

[0048] Therefore, when the processor needs to display the user's heart portrait, it runs the acquired computer program and obtains the target user's ECG signal from the memory. The ECG signal at this time may be an ECG physiological signal. Further, the processor processes the ECG signal, extracts features, and determines ECG events or heart states. The ECG signal may be collected by an ECG sensor and stored in the memory.

[0049] In one embodiment, the ECG event includes any one of the following: sinus tachycardia, sinus bradycardia, normal sinus rhythm, sinus arrhythmia, atrial premature beats, ventricular premature beats, and atrial fibrillation, and the heart state includes any one of the following: relatively fast heart rate, abnormal Q wave, abnormal T wave, and inverted P wave. Therefore, the processor generates a corresponding heart image according to any one of the ECG events: sinus tachycardia, sinus bradycardia, normal sinus rhythm, sinus arrhythmia, atrial premature beats, ventricular premature beats, and atrial fibrillation, or any one of the heart states: relatively fast heart rate, abnormal Q wave, abnormal T wave, and inverted P wave, through a neural network model or simulation, and displays the heart image on a display interface of a heart image display device.

In the process of displaying the heart image, the electrocardiogram signal of the target user is converted into a heart image that can be intuitively understood, so that the user can more intuitively and conveniently understand the monitored heart condition of his or her heart rate index and heart rhythm index according to the heart image, thereby enabling the user to more intuitively and conveniently understand his or her heart health condition.

[0051] In one embodiment, determining an ECG event or a cardiac state based on the ECG signal includes:

[0052] Performing baseline filtering and / or high-frequency noise filtering on the electrocardiogram signal;

[0053] Perform feature extraction on the processed ECG signal to obtain preset ECG signal parameters;

[0054] The ECG event or the heart state of the ECG signal is determined according to the preset ECG signal parameters.

[0055] Specifically, the processor performs baseline filtering and / or high-frequency noise filtering on the ECG signal, wherein the baseline filtering method includes any one of the following: median filtering, wavelet transform, Kalman filtering, first-order difference filtering, Savitzky-Golay filtering, and the high-frequency noise filtering method includes any one of the following: mean filtering, median filtering, first-order lag filtering, second-order lag filtering, and Butterworth filtering.

Second-order lag filtering: performing another filtering on the basis of the first-order lag filtering can further remove high-frequency noise. Butterworth filter: a commonly used digital filter, which adopts the finite impulse response filter design, and the cutoff frequency can be set as needed.

[0056] Further, the processor performs feature extraction on the processed ECG signal to obtain preset ECG signal parameters, wherein the preset ECG signal parameters include: PQRST wave characteristic value, heart rate and heart rate variability. Further, the processor determines the ECG event or heart state of the ECG signal according to the preset ECG signal parameters. In some embodiments, a machine learning algorithm (such as a vector machine, a decision tree, etc.) can be used to train a classifier, which can judge the ECG event or heart state according to the preset parameters. The preset ECG signal parameters are input into the trained classifier to obtain the predicted ECG event or heart state.

[0057] During the process of displaying the heart portrait, the embodiment of the present invention converts the target user's electrocardiogram signal into a heart portrait that can be intuitively understood, so that the user can more intuitively and conveniently understand the monitored heart condition of his or her heart rate index and heart rhythm index based on the heart portrait, thereby allowing the user to more intuitively and conveniently understand his or her heart health status.

[0058] Furthermore, the processor displays heart health prompt information on the display interface of the heart portrait according to the electrocardiogram event or the heart state.

[0059] Further, the processor receives ambient temperature data or body temperature data of the target user, determines the background color of the display interface of the heart image according to the ambient temperature data and / or body temperature data, and displays the background color of the display interface of the heart image.

[0060] Furthermore, the processor displays a weather icon on the display interface of the heart portrait according to the weather forecast information of the day.

[0061] The embodiment of the present invention combines ambient temperature data, body temperature data, weather forecast information for the day and heart portrait, so that the user can better understand the current heart condition and take measures to protect heart health.

Therefore, the processor generates a corresponding heart image according to any one of the ECG events: sinus tachycardia, sinus bradycardia, normal sinus rhythm, sinus arrhythmia, atrial premature beats, ventricular premature beats, and atrial fibrillation, or any one of the heart states: relatively fast heart rate, abnormal Q wave, abnormal T wave, and inverted P wave, through a neural network model or simulation, and displays the heart image on a display interface of a heart image display device.

[0069] Furthermore, the specific process of the processor processing the ECG signal, extracting features, and determining the ECG event or heart state is analyzed as follows:

[0070] Specifically, the processor performs baseline filtering and / or high-frequency noise filtering on the ECG signal, wherein the baseline filtering method includes any one of the following: median filtering, wavelet transform, Kalman filtering, first-order difference filtering, Savitzky-Golay filtering, and the high-frequency noise filtering method includes any one of the following: mean filtering, median filtering, first-order lag filtering, second-order lag filtering, and Butterworth filtering. For mean filtering: taking the average value of the ECG signal within a time window can remove high-frequency noise. Median filtering: taking the median of the ECG signal within a time window can remove abnormal values ​​such as salt and pepper noise. First-order lag filtering: removing high-frequency noise by weighted averaging the signals at the current time point and the previous time point. Second-order lag filtering: performing another filtering on the basis of the first-order lag filtering can further remove high-frequency noise. Butterworth filter: a commonly used digital filter, which adopts the finite impulse response filter design, and the cutoff frequency can be set as needed.

[0071] Further, the processor performs feature extraction on the processed ECG signal to obtain preset ECG signal parameters, wherein the preset ECG signal parameters include: PQRST wave characteristic value, heart rate and heart rate variability. Further, the processor determines the ECG event or heart state of the ECG signal according to the preset ECG signal parameters. In some embodiments, a machine learning algorithm (such as a vector machine, a decision tree, etc.) can be used to train a classifier, which can judge the ECG event or heart state according to the preset parameters. The preset ECG signal parameters are input into the trained classifier to obtain the predicted ECG event or heart state.

[0072] Furthermore, the processor displays heart health prompt information on the display interface of the heart portrait according to the electrocardiogram event or the heart state.
