Q—T 间期延长是出于各种原因引起的心室复极延迟,是产生室性心律失常和猝死的重要原因。本文就我院8年来住院患者中心电图 Q—T 间期延长并恶性室性心律失常的20例进行分析,并就 Q—T 延长诱发恶性室性心律失常和猝死的原因、扭转型室速及治疗等略加讨论。临床资料本文20例均系我院内科住院患者,心电图有 Q—T(Q—Tc)延长及恶性室性心律失常(包括心室颤动和室性心动过速伴晕厥或血液动力学障碍)。其中男性13例,女性7例;年龄从17岁至74岁,40岁以上占18例。20例均为继发性 Q—T 间期延长。埋植永久心脏起搏器4例,死亡9例(包括猝死6例)。
Q-T interval is prolonged for a variety of reasons ventricular repolarization delay, is an important cause of ventricular arrhythmia and sudden death. In this paper, our hospital 8 years of hospitalized patients with Q-T interval prolongation and malignant ventricular arrhythmia in 20 cases were analyzed and Q-T prolonged induced malignant ventricular arrhythmia and sudden death of the reasons, reverse the ventricular tachycardia and Treatment is slightly discussed. Clinical data 20 cases were hospitalized in our hospital in patients with electrocardiogram Q-T (Q-Tc) prolongation and malignant ventricular arrhythmias (including ventricular fibrillation and ventricular tachycardia with syncope or hemodynamic disorders). Among them, 13 were males and 7 were females. The age ranged from 17 to 74 years old, with 18 over 40 years old. 20 cases were secondary Q-T interval prolongation. Four permanent cardiac pacemakers were implanted and 9 died (including 6 cases of sudden death).
