This article documents the termination of a pacemaker endless loop tachycardia by a critically timed atrial extrasystole. Although predictable electrophysiologically, this mode of termination has not been previously reported. The observation is conceptually important because it provides the final link in establishing the similarity of endless loop tachycardia and spontaneous reentrant AV nodal or junctional tachycardias in terms of initiation and termination by single atrial or ventricular extrasystoles.
本文记录了通过适时出现的房性期前收缩终止起搏器无休止环性心动过速的情况。尽管从电生理学角度来看是可预测的，但这种终止方式此前尚未见报道。该观察结果在概念上具有重要意义，因为它为确立无休止环性心动过速与自发性折返性房室结或交界性心动过速在由单个房性或室性期前收缩引发和终止方面的相似性提供了最后一个环节。
