心室间隔支(或称中隔支)传导阻滞,或称心室前向传导延迟,是近年来提出的一个新课题。本症主要特征为前向电力增大,常与引起前向电力增大的其他因素相混淆,其鉴别有一定的临床意义。早在1972年Demoulen等进行组织学研究,即发现左束支除分为左前上及左后下两个分支外,尚存在一个抵达室间隔中部中央区的室间隔支。 Ventricular septal branch (or called the septal branch) block, or forward ventricular conduction delay, is proposed in recent years a new topic. The main feature of this disease is increased forward power, often caused by other factors that increase the forward power confusion, the identification of a certain clinical significance. As early as 1972, Demoulen and other histological studies, that left bundle branch was divided into left upper left and lower two branches, there is a central ventricular septum to reach the central ventricular septal branch.
