(verify) Amiodarone is an antiarrhythmic medication used to treat and prevent a number of types of irregular heartbeats. This includes ventricular tachycardia (VT), ventricular fibrillation (VF), and wide complex tachycardia, as well as atrial fibrillation and paroxysmal supraventricular tachycardia.
Although the U.S. Food and Drug Administration (FDA) has labeled amiodarone only for the treatment of life-threatening ventricular arrhythmias, the drug also is used to treat atrial fibrillation. Because of the complexity and widespread use of this agent, other treatment decisions often are affected.
