Two cases with coupled ectopic ventricular rhythm associated with artificial pacing are presented. The premature ventricular beats appeared at a fixed distance from the R of the previous electrical stimulus complex and when pacing was stopped ventricular arrest occurred. This provides strong evidence that the ectopic ventricular beats were dependent on the electrical stimulus and therefore that they were produced by its re-entry. It was observed that the re-entry phenomenon occurred at low rates. This arrhythmia even persisted after the permanent pacing and was successfully suppressed by procainamide in both cases.
本文报告两例与人工起搏相关的耦合性室性异位心律。室性早搏出现在距前一个电刺激复合波的R波固定距离处，当起搏停止时发生心室停搏。这有力地证明了室性异位搏动依赖于电刺激，因此是由其折返产生的。观察到折返现象在低频率时发生。这种心律失常在永久性起搏后仍持续存在，两例均被普鲁卡因胺成功抑制。
