Technical Field

The utility model belongs to heart monitoring field especially relates to a portable heart monitoring devices.

Background

Currently, the clinical medicine mainly uses Electrocardiogram (ECG) for heart detection, and the instruments required by this method are often bulky and cannot monitor the heart condition at any time. More importantly, the method can only measure the cardiac electrical signals and cannot reflect the mechanical activity states of the heart, such as the motion state of a heart valve, the blood circulation state of a ventricle, the wall state of the ventricle and the like, so that a blind area exists in the judgment of the heart state.

Therefore, it is necessary to develop a real-time monitoring device by combining the electrocardiographic signal and the cardiac shock signal, so as to collect the electrocardiographic signal and the cardiac shock signal of the wearer in real time, and send the processed result to the mobile device, so that the user can comprehensively master the heart state.

Chinese patent publication No. CN 108471948A, entitled health monitor patch, discloses a health monitor patch that can monitor cardiac waveforms, activities performed by a subject, and body orientation of a subject. The health monitor patch cannot collect a heart-shaking signal and cannot reflect heart mechanical activity states such as a heart valve motion state, a ventricle blood circulation state, a ventricle wall state and the like, so that the analysis of the heart state is not comprehensive enough.

Some activity monitors worn on the subject's wrist or ankle may be suitable for sensing heart rate, but these monitors typically cannot measure details of the heart waveform to obtain information such as heart rate variability or cardiac abnormalities such as arrhythmias, resulting in an less comprehensive analysis of the heart condition.
