Therapeutic Flecainide Toxicity Causing VT Storm

Abstract

Ventricular tachycardia (VT) storm is a fatal arrhythmia with multiple contributory etiologies. This paper presents a case of a 71-year-old woman who developed VT storm from flecainide toxicity occurring at therapeutic flecainide levels. Flecainide toxicity should be considered in any patient on flecainide presenting with VT.
