Efficacy and safety of ibutilide for the conversion of monomorphic atrial tachycardia.

Background: Ibutilide is a class III antiarrhythmic drug, frequently used for conversion of atrial fibrillation and flutter. We studied the efficacy of ibutilide for acute conversion of monomorphic atrial tachycardia (monoAT) in a prospective, open label study in the intensive care unit of a cardiological clinic.

Methods: We examined 49 episodes of monoAT in 38 patients (19 men/19 women).
