Abstract

A His bundle electrogram was obtained in a 70 year old male with syncopal episodes. A split bundle of His deflection was recorded. After the intravenous administration of phentolamine, a marked shortening of the H-H' interval was observed. This signifies an improvement in conduction at the bundle of His level.

摘要

对一名有晕厥发作的70岁男性进行了希氏束电图检查。记录到希氏束波分裂。静脉注射酚妥拉明后，观察到H-H′间期明显缩短。这表明希氏束水平的传导得到改善。
