Why the study?
Does intravenous infusion of ibutilide, propafenone, or amiodarone improve conversion rates and alter electrophysiologic parameters in patients with typical atrial flutter?
Does intravenous infusion of ibutilide, propafenone, or amiodarone improve conversion rates and alter electrophysiologic parameters in patients with typical atrial flutter?
Ibutilide is more effective than propafenone and amiodarone for the acute conversion of typical atrial flutter due to its unique ability to increase atrial refractoriness.

May inform acute typical atrial flutter management; hypothesis-generating in small cohort and leaves open randomized confirmation.
