If wide-complex tachycardia is present and the diagnosis of ventricular tachycardia (VT) cannot be excluded, the drugs of choice are IV procainamide or amiodarone (in lieu of cardioversion if the patient is stable hemodynamically; see below). Ibutilide may also be useful in this setting (also class III). Lidocaine is not useful for preexcited atrial fibrillation.
