title: Flecainide-induced sustained ventricular tachycardia successfully treated with lidocaine.
abstract: A 69-year-old man had new sustained ventricular tachycardia caused by flecainide which promptly responded to intravenous lidocaine therapy. Discontinuation of the lidocaine infusion resulted in the reappearance of ventricular tachycardia which again immediately terminated after lidocaine was given. In this case, lidocaine effectively reversed the proarrhythmic effects of flecainide.
