With rapid development and support of medical, computer and internet technologies, remote electrocardiography (ECG) monitoring is becoming more and more mature. Currently, remote ECG monitoring, as an important method for cardiology-related remote medical monitoring, plays a decisive role in pre-hospital first aid, remote diagnosis and follow-up management. Remote ECG monitoring can more easily capture the ECG in case of sudden or transient symptoms, provide timely diagnosis and treatment for high-risk groups of cardiovascular diseases, decrease the rates of missed diagnosis and misdiagnosis of cardiovascular events, and reduce the social economic and medical burden. Therefore, it has a good application and development prospect.
