Two cases which exhibited a Wenckebach form of exit conduction between an electrical pacemaker and the ventricular myocardium are presented. This manifests with increasing latency (stimulus to QRS intervals) and ultimate stimulus failure (block). The cycle then repeats itself. The QRS duration also increases progressively within each cycle. The phenomenon connotes an adverse prognosis. Several postulates regarding the mechanism are discussed.
本文介绍了两例在心脏起搏器与心室心肌之间呈现文氏型传出传导的病例。这种情况表现为潜伏期（刺激至QRS波间期）逐渐延长，最终刺激失败（阻滞）。然后该周期重复出现。每个周期内QRS波时限也逐渐增加。这种现象意味着预后不良。文中讨论了关于其机制的几种假设。
