自1961年Durrer在实验犬缺血心肌首次记录到晚电位以来,Josephson、Simson等许多学者先后经心内膜、心外膜直视探测和心内导管标测以及体表信号平均心电图(SAECG)记录到人体心室晚电位(VLPs)。这种由心肌1个或多个病变部位除极延迟所致的,出现于心室除极化结束时的局部心肌电活动,是局部心肌传导迟缓的 Since Durrer first recorded late potential in experimental canine ischemic myocardium in 1961, many scholars such as endocardial, epicardial exploration and intracardiac catheterization and SAECG have been followed by many scholars such as Josephson and Simson. Recorded to human ventricular late potential (VLPs). This is caused by the depolarization delay of one or more lesions in the myocardium and local myocardial electrical activity at the end of ventricular depolarization,
