Heart disease includes congenital heart disease and acquired heart disease. The former is mainly concentrated in infants and young children, while the latter is common in middle-aged and elderly people. Studies have shown that if abnormal heart rhythms can be detected in time, and corresponding measures can be taken, heart disease can be greatly reduced. morbidity and mortality.

However, currently most of the equipment used for cardiac rhythm monitoring is professional testing equipment adopted by hospitals, which includes ECG collection and analysis equipment and lead equipment electrically connected to the ECG collection and analysis equipment. The lead equipment generally includes a large number of detection electrodes, especially in order to obtain an electrocardiogram with medical diagnostic value, more than 12 electrocardiograms are required. To satisfy 12-lead ECG detection, signals from 10 electrodes need to be obtained. These electrodes are all active electrodes. Due to the large number of lines and complicated positioning, non-professional testing doctors are not competent; therefore, it is difficult for ordinary individuals to complete professional ECG testing.

Although there are some ECG detection equipment specially designed for individuals on the market, the structure is complicated and heavy, it is not conducive to carrying, and the operation is also very troublesome. It needs to be placed in a fixed place for use; It is very necessary to detect ECG signals in real time under certain conditions, but the current equipment cannot meet the randomness requirements of ECG detection. Existing personal ECG detection equipment can only be used in fixed occasions in the home, and it is inconvenient to carry when moving, and there is no automatic warning function of cardiac pacing abnormality and electrode detachment detection function, which is not conducive to operation and use.

The installation of a permanent cardiac pacemaker is used as an aftereffect method to treat heart diseases, and the number of people who have installed a permanent cardiac pacemaker has been increasing in recent years. The electrocardiogram can record the abnormal performance of pacing function in various situations, which can reflect the patient's ECG changes in daily life, so ECG is often used as an effective means of functional follow-up evaluation after pacemaker implantation, but the existing detection equipment obviously cannot meet the requirements of this kind of all-weather ECG detection.
