Long-term outcome in patients with chronic atrial fibrillation after successful internal cardioversion

Am J Cardiol. 1999 Feb 15;83(4):607-9, A8, A10. doi: 10.1016/s0002-9149(98)00925-4.


Internal cardioversion is safe and effective in restoring sinus rhythm, even in patients with persistent AF of prolonged duration. Up to 40% to 50% of patients with AF lasting >1 year but <3 years could be maintained in sinus rhythm using a class III antiarrhythmic drug after successful internal cardioversion, and amiodarone appears to be more effective than sotalol in this patient population.
