[0038] A method for monitoring the heart based on a wearable device provided by an embodiment of the present invention is introduced in detail.

[0039] refer to figure 1 , shows a flow chart of a method for monitoring the heart based on a wearable device in an embodiment of the present invention, the wearable device includes a heart signal sensor and a monitoring chip connected to the heart signal sensor, and the heart signal sensor The electrode adopts piezoelectric film, and the heart signal sensor is attached to the chest or back of the human body.

[0040] In this embodiment, a wearable device for monitoring the heart is provided. The device includes a heart signal sensor and a monitoring chip, and the monitoring chip is connected to the heart signal sensor for acquiring cardiac shock signals and ECG signals, and analyzing the cardiac shock signals. The electrodes of the heart signal sensor may be piezoelectric films or other materials, which are not limited in detail in...

Embodiment 2

[0052] refer to figure 2 , shows a flowchart of a method for monitoring a heart based on a wearable device in another embodiment of the present invention.

[0053] Step 201 , the monitoring chip acquires the cardiac shock signal and ECG signal monitored by the cardiac signal sensor in real time.

[0054] Step 202, searching for the peak of the first cardiac shock signal aligned with the peak of the first ECG signal.

[0055] In this embodiment, the period of the cardiac shock signal is determined according to the period of the electrocardiographic signal. First, the first peak of the electrocardiographic signal is found, and the peak of the cardiac shock signal aligned with the first peak of the electrocardiographic signal is the one to be searched. The first peak of the cardiac shock signal is the beginning of a cycle of the cardiac shock signal. The peak of the cardiac shock signal may be the H peak or the J peak, which is not limited in detail in the embodiment of the pr...

Abstract

The invention provides wearable equipment and a method for monitoring the heart on the basis of the wearable equipment. The wearable equipment includes a cardiac signal sensor and a monitoring chip connected with the cardiac signal sensor, piezoelectric film is adopted as the electrode of the cardiac signal sensor, and the cardiac signal sensor is attached to the front chest or the back of the human body; the method includes the steps that the monitoring chip obtains a cardiac impulse signal and an electrocardio signal which are monitored by the cardiac signal sensor in real time; according tothe cycle of the electrocardio signal, the cycle of the cardiac impulse signal is determined; according to the cycle of the cardiac impulse signal, an abnormal event of the cardiac impulse signal isidentified. By adopting the same sensor for monitoring the cardiac impulse signal and the electrocardio signal at the same time, the two signals are supplemented and rectified by each other, not onlycan a heart disease be diagnosed by means of the electrocardio signal, but also the heart disease can be predicted by means of the cardiac impulse signal.

Description

technical field [0001] The invention relates to the field of wearable devices, in particular to a wearable device and a method for monitoring a heart based on the wearable device. Background technique [0002] Chronic diseases can be seen everywhere in today's society, and people are beginning to pay more attention to monitoring their health status. Statistics from the World Health Organization in 2005 showed that the mortality rate of cardiovascular and cerebrovascular diseases reached 42.3%, accounting for the first place in the mortality rate. When a heart attack occurs, the heart rhythm changes significantly. Heart disease can be diagnosed or predicted by monitoring the heart, so that people can treat or prevent it early. [0003] The basic activity of the heart includes electrical activity and mechanical activity, which are monitored by ECG and BCG, respectively. ECG (electrocardiogram, electrocardiogram) is the heart in each cardiac cycle, the pacemaker, the atrium,...
