尖端扭转型室性心动过速(以下简称Tdp)是一种特殊类型的心律失常。法国学者 Dessertene1966年首次作了描述,并冠之以“Torsadesdepointes”这一形象化的名称。临床表现Tdp 发作持续数秒钟以上即可发生昏厥与抽搐,常反复发作,其症状与发作时间一致。当 Tdp 连续发作多次,特别是与心脏停搏交替发生时,可导致昏迷。当恶化为室颤时血压为零。 Torsades de pointes (Tdp) is a special type of arrhythmia. Dessertene, a French scholar, first completed his martyrdom in 1966 with the visualization of “Torsades depointes”. Clinical manifestations of Tdp episodes lasts for more than a few seconds can occur syncope and convulsions, often repeated attacks, the symptoms consistent with the attack time. When the Tdp continuous episodes many times, especially when alternating with cardiac arrest can lead to coma. Blood pressure is zero when worsening to ventricular fibrillation.
