CME ECG 66/Answers: Torsade de Pointes: The Danger of a Rotating Heart Axis Torsade de pointes tachycardia is a potentially life-threatening heart rhythm disorder, caused by prolongation of the QT interval resulting in triggered activity. This QT prolongation can be congenital or acquired. If acquired, it is mainly caused by pharmacological therapy. The hallmark of torsade de pointes is an undulating QRS axis with a twist of the QRS complex around the ECG's baseline. Often, this polymorphic ventricular tachycardia is self-limiting, but degeneration into ventricular fibrillation is possible, which makes torsade de pointes tachycardia dangerous. This article aims to provide insights into etiology, diagnostics, prevention and management of this heart rhythm disorder.
继续医学教育心电图66/答案：尖端扭转型室速：心脏轴旋转的危险 尖端扭转型室速是一种潜在的危及生命的心律失常，由QT间期延长导致触发活动引起。这种QT间期延长可为先天性或后天获得性。如果是后天获得性的，主要由药物治疗引起。尖端扭转型室速的特征是QRS轴波动，QRS波群围绕心电图基线扭转。通常，这种多形性室速是自限性的，但有可能恶化为心室颤动，这使得尖端扭转型室速很危险。本文旨在深入探讨这种心律失常的病因、诊断、预防和管理。
