Electrical ventricular separation, as a special complete intraventricular block, denotes that ventricles be electrically separated into two or more parts caused by severe and wide damage of myocardium and conduction. Electrical ventricular separation can be divided into homologous and heterologous, homologous electrical ventricular separation is a rare phenomenon, literally the excitement of whole ventricle originate from supraventricle, on ECG, there are two different QRS waves which connect with an isoelectric line, one ST segment and T wave. We report a valve heart disease presented with complicated electrophysiological characteristics, which has reversed complex homologous electrical ventricular separation with second degree intraventricular block.
电心室分离作为一种特殊的完全性室内阻滞，是指心室因心肌和传导系统的严重广泛损害而电活动分离为两个或更多部分。电心室分离可分为同源性和异源性，同源性电心室分离是一种罕见现象，从字面上讲，整个心室的激动起源于室上，心电图上有两个与等电线相连的不同QRS波、一个ST段和T波。我们报告一例具有复杂电生理特征的瓣膜性心脏病，其呈现出伴有二度室内阻滞的逆向性复杂同源性电心室分离。
