扭转型室性心动过速(Torsades depointes,简称TDP)是一种特殊类型快速室性心律失常,无论在心电图特征、临床表现、病因和发病机理,以及治疗等方面均与人们所熟悉的早搏型室性心动过速和心室颤动迥然不同。虽然它早在30余年前已被描述,但皆被误为心室颤动。Schwarfz在1949年首先指出其发作的特点为短暂性且可自行消失,因而称为“短暂性心室颤动”。以后又由其他作者以“室颤前室速”、“假性室颤”、“心脏芭蕾舞”等名称予以报道。直至1966年由法国的Dessertenne等对TDP的心电图和临床表现作了系统的描述。近几年来才逐渐被确认为一种室性心律失常的类型。
Torsades depointes (TDP) is a special type of rapid ventricular arrhythmia, both in electrocardiogram characteristics, clinical manifestations, etiology and pathogenesis, and treatment are familiar with the familiar type of premature beats Ventricular tachycardia and ventricular fibrillation are very different. Although it was described more than 30 years ago, it was mistaken for ventricular fibrillation. Schwarfz first pointed out in 1949 that the episode was transient and self-defeating and was therefore referred to as “transient ventricular fibrillation.” Later by other authors to “pre-ventricular VT”, “pseudo-ventricular fibrillation”, “heart ballet” and other names to be reported. Until 1966 by the French Dessertenne et al on TDP ECG and clinical manifestations were described. In recent years it has gradually been identified as a type of ventricular arrhythmia.
