title: Paroxysmal atrial fibrillation precipitated by amiodarone-induced thyrotoxicosis five months after cessation of therapy.
abstract: Amiodarone is currently indicated for the treatment of life-threatening ventricular dysrhythmias. It is also used for the treatment of supraventricular dysrhythmias and as maintenance therapy after successful cardioversion of atrial flutter or atrial fibrillation. Adverse effects related to its expanded use are increasingly common. We describe a case of amiodarone-induced thyrotoxicosis occurring 5 months after cessation of therapy and discuss the pathophysiology and treatment of this disorder.
