We reported a case of inappropriate implantable cardioverter defibrillator shocks, due to atrial far-field on the tip-to-ring channel of the fast electrical activity during atrial fibrillation, caused by lead dislocation in the right ventricle outflow tract. During these episodes the can-to-right ventricle coil signal correctly recorded the ventricular activity. The shock storm stopped when an antitachycardia pacing restored sinus rhythm.
我们报告了一例不适当的植入式心脏复律除颤器电击事件，其原因是右心室流出道导线脱位导致房颤期间快速电活动的尖端至环通道出现心房远场信号。在这些发作期间，罐至右心室线圈信号正确记录了心室活动。当抗心动过速起搏恢复窦性心律时，电击风暴停止。
