体表电位是心起动力的兴奋过程在体表上电势的表现,即体表心电图。由体表心电位去推断心动全周期中心脏不同部位的心肌兴奋所产生的电动势的大小,作为临床上诊治的一种手段。这就是心电图的逆问题。它具有重要的临床意义。心电图逆问题可和x射线的CT相当的,可以无损伤诊断W—P—W病,心肌梗塞的面积大小等。为诊断心脏 Body surface potential is the starting process of excited excitement in the body surface potential performance, the body surface ECG. From the body surface to determine extrapolation of heart electrocardiogram throughout the cardiac cycle in different parts of the cardiac EMF generated by the size as a means of clinical diagnosis and treatment. This is the inverse problem of ECG. It has important clinical significance. ECG inverse problem can be comparable with x-ray CT, can be non-invasive diagnosis of W-P-W disease, myocardial infarction area size. To diagnose the heart
