Ibutilide versus amiodarone in atrial fibrillation: a double-blinded, randomized study.

Objective: Ibutilide, a class III antiarrhythmic drug, has been shown to convert atrial fibrillation to sinus rhythm more rapidly than procainamide or sotalol. Our objective was to compare the efficacy and safety of ibutilide and amiodarone in patients after cardiac surgery.

Design: Prospective, randomized, double-blinded study.
