Abstract: The electrocardiography (ECG) telemonitoring system is briefly introduced, especially the development progress, including the wearable technology. For early cardiac rehabilitation (CR) after acute myocardial infarction (AMI), the ECG telemonitoring system can monitor heart rate, blood pressure, heart rate recovery (HRR), which is confirmed to assess autonomic nervous function; as well as rate pressure product (RPP), which is confirmed to speculate lactate anaerobic threshold during CR, can be calculated to guide the exercise intensity of CR progress. Finally, the legal liability issues if accidents occurred in home-based CR program, and the innovation, such as combining with the network, are discussed.

Key words: electrocardiography telemonitoring system, acute myocardial infarction, cardiac rehabilitation, review
