Abstract
Prolongation of the QT interval and development of torsades de pointes are known in patients with complete heart block and profound bradycardia. We report the case of a patient with complete heart block and torsades, with long QT seen during a period of junctional tachycardia at a rate faster than the minimum pacemaker rate.
摘要
完全性心脏传导阻滞和严重心动过缓的患者已知会出现QT间期延长和尖端扭转型室速。我们报告了一例完全性心脏传导阻滞并伴有尖端扭转型室速的患者，在交界性心动过速期间观察到QT间期延长，其心率快于最低起搏心率。
