TORSADES DE POINTES IN ELDERLY PATIENT WITH PAROXYSMAL ATRIAL FIBRILLATION TREATED BY SHORT-TERM PARENTERAL AMIODARONE THERAPY

Abstract

One of the drugs that are widely used in the treatment of atrial fibrillation is amiodarone. Despite considerable prolongation of the corrected QT interval and a substantial degree of bradycardia, amiodarone exhibits a remarkably low frequency of pro-arrhythmic events and <1.0% incidence of torsades de pointes, mostly after long-term usage. We present a case of an 80-year-old female with paroxysmal atrial fibrillation accompanied by acute heart failure treated by short-term parenteral amiodarone therapy and development of torsades de pointes.
