A 66-year-old woman underwent successful radiofrequency catheter ablation for long-lasting, drug refractory fast atrial flutter. Two days later she had a cardiac arrest due to torsades de pointes (TdP) tachycardia attributed to relative sinus bradycardia and QT interval prolongation. After successful resuscitation further episodes of TdP occurred, which were treated with temporary pacing. Because of concomitant systolic dysfunction due to ischemic and valvular heart disease she was finally treated with an implantable defibrillator. In conclusion we strongly advise prolonged monitoring for 2 or more days for patients with structural heart disease following successful catheter ablation for long lasting tachyarrhythmias.
一名66岁女性因长期药物难治性快速心房扑动接受了成功的射频导管消融术。两天后，她因尖端扭转型室性心动过速（TdP）导致心脏骤停，该TdP心动过速归因于相对窦性心动过缓和QT间期延长。成功复苏后，TdP再次发作，采用临时起搏治疗。由于存在缺血性和瓣膜性心脏病导致的收缩功能障碍，她最终接受了植入式除颤器治疗。总之，对于患有结构性心脏病且成功进行导管消融治疗持久性快速心律失常的患者，我们强烈建议进行持续2天或更长时间的监测。
