Recurrent ventricular fibrillation was observed in a 67-year-old woman following catheter ablation of the AV junction using radiofrequency energy. This serious complication has been reported following direct current energy ablation of the AV junction, but not after using radiofrequency energy. This life-threatening arrhythmia seemed pause and bradycardia dependent. It was followed by QTc prolongation of the QRS escape rhythm 1 day after the procedure. Ventricular arrhythmias were suppressed by rapid ventricular pacing.
一名67岁女性在使用射频能量进行房室结导管消融术后出现反复室颤。这种严重并发症在直流电能量消融房室结后已有报道，但在使用射频能量后未见报道。这种危及生命的心律失常似乎与停顿和心动过缓有关。术后1天，QRS逸搏心律出现QTc延长。快速心室起搏可抑制室性心律失常。
