Description

Technical field [0001] The invention relates to a non-contact twelve-lead ECG signal acquisition device, which belongs to the field of medical electronics. Background technique [0002] The electrocardiogram reflects the bioelectric discharge state of the human heart. Abnormal myocardial discharge represents a certain abnormality in the mechanical movement of the heart. Therefore, the electrocardiograph is widely used in clinical diagnosis in hospitals and can be used for low-cost, rapid and accurate screening of cardiovascular diseases. Check, diagnosis, postoperative and medication evaluation. With the development of the Internet of Things technology, ECG signal acquisition circuits have gradually developed in the direction of high integration and low power consumption. Therefore, various wearable ECG signal acquisition devices have emerged, making ECG devices more suitable for daily life scenarios, especially It is used for real-time monitoring of heart rate during strenuous ...
