We describe a case of an otherwise healthy 50-year-old man with frequent attacks of heart palpitations. During electrophysiological study two episodes of atrial fibrillation (AF) were induced. In both cases AF was preceded by a few seconds of atrioventricular nodal reentrant tachycardia (AVNRT). Ablation of atrioventricular node slow pathway successfully eliminated both tachyarrhythmias during 6 months follow-up. Since during AVNRT a few short coupled atrial ectopic beats appeared, we hypothesized that AVNRT did not trigger AF directly but by inducing ectopic beats form a pulmonary vein or an atrial focus that became a direct trigger of AF.
我们描述了一例50岁身体健康但频发心悸的男性病例。在电生理研究期间诱发了两次心房颤动（AF）发作。在这两例中，AF发作前均有几秒的房室结折返性心动过速（AVNRT）。在6个月的随访期间，消融房室结慢径成功消除了两种快速性心律失常。由于在AVNRT期间出现了一些短联律的房性早搏，我们推测AVNRT并非直接触发AF，而是通过诱发来自肺静脉或心房病灶的异位搏动，而这些异位搏动成为AF的直接触发因素。
