Termination of acute wide QRS complex atrial fibrillation with ibutilide.
Ibutilide is a Vaughan-Williams class III antiarrhythmic agent approved for chemical cardioversion of acute onset atrial fibrillation/flutter. Emergency physicians rarely use ibutilide despite its proven clinical value. We report a case of successful chemical cardioversion using ibutilide in a patient with atrial fibrillation and delayed ventricular depolarization (wide QRS complex). We recommend that ibutilide be considered for wider use in the emergency department and that further studies be conducted.
