INTRODUCTION The QT interval prolongation is an adverse effect associated with moxifloxacin. This adverse effect can lead to potentially life-threatening arrhythmias such as Torsades de pointes. We describe a case of severe QT interval prolongation associated with moxifloxacin which may cause the development of Torsades de pointes. There have been no reported case of severe corrected QT interva...

Torsades de pointes (TdP) is defined as a polymorphic ventricular tachycardia (VT) with a twisting QRS morphology associated with a prolonged QT interval and/or increased U wave amplitude in the ECG.1,2 Patients with acquired or congenital long-QT syndrome (LQTS) can develop TdP that results in sudden cardiac death. Fifty or more drugs, both typical antiarrhythmic agents such as quinidine as we...
