摘　　要：报告18例由Q－T延长所致尖端扭转型室性心动过速的急诊治疗。根据发病前的精神状态和心电监护中于发作前、中、后心电图变化，可将其分为间歇依赖型和肾上腺素能神经依赖型两种类型。根据不同类型分别采用异丙肾上腺素，利多卡因，β－受体阻滞剂，补充钾盐、镁盐及埋值心脏临时起搏器，电除颤复律术等措施，18例均恢复窦性心律。需特别指出，心律平治疗1例本病时，病情恶化为室颤，立即采用电除颤复律术才获抢救成功。The emergency treatment of 18 patients with Torsade de Pointes tachycardia induced by long Q-T interval syndrome was reported. According to the mental states prior to the onsets and the ECG changes before,during and after the onsets, this tachycardia may be classified as two types,that is,intermit-dependent and adrenal-dependent. Based on these types,all patients were reversed into sinus rhythm with isoprenaline,lidocain,β-receptor blocking agents, potassium chloride and magnesium sulfate, installation of temporary pacemaker and electric defibrillation. It is alleged that the propafenone could have aggravated the condition and eventually converted tachycardia into ventricular fibrillation,and this was successfully treated by electric defibrillation.
