This case report describes a 68-year-old woman presenting with flecainide induced syncope due to torsades de pointes (TP) ventricular tachycardia. Before TP onset, the QTc interval reached 680 ms without changes in QRS duration. None of the usual triggers were found. Prolongation of QT under flecaïnide is exceptional and the occurrence of TP without concurrent triggers has not been reported in the literature.
本病例报告描述了一名68岁女性，因氟卡尼诱发尖端扭转型室性心动过速（TP）而出现晕厥。在TP发作前，QTc间期达到680毫秒，QRS时限无变化。未发现任何常见的触发因素。氟卡尼导致QT延长的情况极为罕见，且文献中未报道过无并发触发因素而发生TP的情况。
