药物引起的获得性长QT综合征中由于尖端扭转型室性心动过速引发的心脏骤停尽管罕见但却是致命的,尤其对于住院病人。现综述尖端扭转型室性心动过速的心电图特征、即将发生心律失常的征兆、获得性长QT综合征的细胞学机制、当前对于遗传易感性的认识、最容易引起尖端扭转型室性心动过速的药物、医院内监测QT间期的方法、QT显著延长和尖端扭转型室性心动过速的即刻处理策略等,为尖端扭转型室性心动过速的院内预防提供参考。
Drug Induced Acquired Cardiac arrest due to Torsades de Pointes in Long QT Syndrome is rare but fatal, especially for hospitalized patients. Are summarized in the ECG torsades de pointes tachycardia, the forthcoming signs of arrhythmia, acquired cytology of long QT syndrome, the current understanding of genetic predisposition, the most likely to cause torsades de pointes ventricular tachycardia Rapid medication, QT interval monitoring method in the hospital, QT prolongation and immediate treatment of torsades de pointes (TTPA) and so on, so as to provide a reference for the prevention of torsades de pointes ventricular tachycardia.
