Abstract

Long QT syndrome is a congenital or acquired condition associated with life-threatening cardiac arrhythmias. Risk stratification measures are paramount to providing life-saving therapy. We present a case of a 30-year-old man with syncope and polymorphic ventricular tachycardia from drug-induced QTc prolongation. Electromechanical window negativity correlated with arrhythmia risk and risk predictors. ().

摘要

长QT综合征是一种与危及生命的心律失常相关的先天性或后天性疾病。风险分层措施对于提供挽救生命的治疗至关重要。我们报告一例30岁男性因药物诱导的QTc延长出现晕厥和多形性室性心动过速的病例。机电窗负值与心律失常风险及风险预测因素相关。（）
