Abstract
A patient with the combination of right bundle branch block and intermittent left anterior and left posterior hemiblock is presented. His bundle recordings proved that this type of intraventricular conduction defect appeared when the two left fascicles were damaged partially, and to a varying degree. The recordings also revealed a Grade 2 A-V block distal to the A-V node. The mechanism is discussed.
摘要
本文报告一例合并右束支传导阻滞及间歇性左前分支和左后分支阻滞的患者。其束支电图证实，这种类型的室内传导阻滞是在左束支两分支发生不同程度的部分损害时出现的。记录还显示在房室结远端存在二度房室传导阻滞。并对其机制进行了讨论。
