The authors present an unusual case of torsades de pointes (Tdp) in an elderly woman with a history of aortic stenosis, status post aortic valve replacement. She was admitted for atrial fibrillation with a slow ventricular response. At the time of admission, the patient was asymptomatic and not taking any medications known to be associated with QT prolongation. During hospitalization, she developed episodes of Tdp without any provocable cause. This case highlights the occurrence of Tdp secondary to conduction disturbance caused by aortic valve surgery.
作者报告了一例罕见的尖端扭转型室性心动过速（Tdp）病例，患者为一名老年女性，有主动脉瓣狭窄病史，已行主动脉瓣置换术。她因心房颤动伴缓慢心室反应入院。入院时，患者无症状，未服用任何已知与QT间期延长相关的药物。住院期间，她在无任何可诱发因素的情况下发生了Tdp发作。该病例突出了主动脉瓣手术引起的传导障碍继发Tdp的发生情况。
