摘要
It is very important to redure the body surface electrodes as much as possible in recording ECG clinically. By constructing human heart profile model, based on the characteristic of electrocardic physiology, the authors put forward a new method of weighed epicardial potential to study the relationship between body surface potential and epicardial potential. Thus, the unknown body surface potential could be derived by the selected body surface potential. This method has been proved practical in diagnosing and locating myocardial ischemia and myocardial infarction with stardard 12-lead ECG.
