Amiodarone Induced Torsades De Pointes with Intravenous Therapy for Atrial Fibrillation

Abstract

The case of a 71 year-old woman with rapid atrial fibrillation who underwent electrical cardioversion and amiodarone therapy. QT interval prolongation was observed with the development of torsades de pointes that required recurrent electrical cardioversion and temporal pacemaker implantation. Key Clinical Message : Amiodarone induced torsade de pointes is very rare tachyarrhythmia developed during intravenous therapy for atrial fibrillation. Careful monitoring of the QT interval can prevent development of this life-threatening arrhythmia.
