心电图诊断的临床作用是从体表所得到的波形推断心脏内的状态。直到目前,这个推断过程还是在医生头脑中进行的。根据体表心电图,如果能推断心脏搏动全周期中兴奋心肌细胞位置与电势大小,则作为临床疾病诊断手段的意义是很大的。这种问题一般称为心电图的逆问题(Inverse problem in ECG),是心电图研究中的重要课题之一。 The clinical role of ECG diagnosis is to infer the state of the heart from the waveform obtained from the body surface. Until now, this inference process is still in the minds of doctors. According to the body surface ECG, if we can infer the whole cycle of cardiac beats in excitement of myocardial cell location and potential size, as a means of clinical diagnosis of disease is of great significance. This problem is generally called inverse problem in ECG (ECG), is one of the important topics in ECG research.
