This report described initiation of A-V nodal reentrant tachyycardia in a patient with acute inferior myocardial infarction. The onset of tachycardia was preceded by an abortive A-V nodal Wenckebach periodicity. A-V nodal ischemia with or without vagotonia was implicated as the cause of induction of critical functional dissociation between the two A-V nodal conduction pathways. Since the tachycardia manifested its rate between 95-110 beats/min during the evolutionary phase of acute inferior myocardial infarction, it simulated, electrocardiographically, an accelerated A-V junctional rhythm. Analysis of the onset of tachcardia was of diagnostic importance.
本报告描述了一名急性下壁心肌梗死患者发生房室结折返性心动过速的情况。心动过速发作前有一次顿挫型房室结文氏周期。伴有或不伴有迷走神经张力增高的房室结缺血被认为是导致两条房室结传导通路之间关键性功能分离的原因。由于在急性下壁心肌梗死演变期心动过速的心率在95 - 110次/分钟之间，在心电图上模拟了加速性房室交界区心律。分析心动过速的发作具有诊断意义。
