摘　　要：目的:探讨获得性QT间期延长伴尖端扭转室性心动过速的原因及临床治疗。方法:回顾性分析我院2006年到2011年收治的26例获得性QT间期延长伴尖端扭转室性心动过速患者的临床资料,分析26例患者的临床表现、心电图特点、观察其临床治疗结果。结果:26例患者均有明确的诱发因素,其中9例为合并束支传导阻滞窦性心动过缓,7例为药物诱发,5例为心房颤动、心力衰竭,3例为传导阻滞,2例为风湿性心脏瓣膜病、二尖瓣狭窄并发心房颤动。治疗前后平均QTc分别为(615±17)ms及(455±12)ms,26例患者积极治疗原发病,结合补钾、补镁配合治疗。结论:密切监测心电图及QTc变化,是早期识别并正确治疗治疗获得性QT间期延长伴尖端扭转室性心动过速的关健。Objective： To discuss reasons and clinical treatment of acquired QT interval prolongation associated with torsades de pointes ventricular tachycardia. Methods： Retrospective analysis of clinical data of 26 patients admitted to our hospital from 2006 to 2011, analysis of the clinical manifestations, ECG characteristics, and treatment results. Results： Patients had clear predisposing factor, 9 cases was merger bundle-branch block with sinus bradycardia, 7 cases was drug-induced, 5 cases was atrial fibrillation, heart failure, 3 cases was the block, 2 cases was rheumatic heart disease, mitral stenosis and atrial fibrillation. Conclusion： Close monitoring of ECG and QTc changes is the key of correct treating acquired QT interval prolongation associated with torsades de pointes ventricular tachycardia.
