近20年来,从事于心脏病的研究工作者对心室内传导系统的分支进行了大量研究工作。这些研究阐明了心室内分支及双侧束到阻滞的原因,临床心电图表现和预后意义;澄清了不少以前不理解的心电图现象。例如对Wilson于1934年提出的“右束支阻滞的一种少见类型的心电图”及Richman和Wolff于1954年所提出的“伪装为右束支阻 For nearly two decades, researchers engaged in heart disease have done a great deal of research on the branches of the ventricular conduction system. These studies have elucidated the causes of ventricular branches and bilateral bundle-to-block, clinical ECG findings, and prognostic implications; clarified a number of previously unread ECG phenomena. For example, in Wilson’s 1934 “a rare type of right bundle branch block ECG” and Richman and Wolff in 1954 proposed "disguised as right bundle branch block
