A 61-year-old man presented with symptomatic 2 degree Mobitz II AV block in association with bifascicular block. Ventricular pacing resulted in temporary depression of AV conduction. The extent of pacing-induced AV block varied directly with the duration and rate of ventricular pacing. Intracardiac recordings proved that the site of spontaneous and pacing-induced AV block was distal to the His bundle. Possible mechanisms by which this phenomenon may arise and several implications of practical importance are discussed.
一名61岁男性患者表现为伴有双分支阻滞的症状性二度莫氏Ⅱ型房室传导阻滞。心室起搏导致房室传导暂时抑制。起搏诱导的房室传导阻滞程度与心室起搏的持续时间和频率直接相关。心内记录证实，自发和起搏诱导的房室传导阻滞部位均在希氏束远端。本文讨论了这种现象可能出现的机制以及一些具有实际重要意义的影响。
