Prospective assessment of the minimum energy needed for external electrical cardioversion of atrial fibrillation

Am J Cardiol. 1997 Mar 15;79(6):815-6. doi: 10.1016/s0002-9149(96)00879-x.


This study demonstrates that shocks <200 J often are effective for transthoracic cardioversion of atrial fibrillation (AF). Lower energy shocks are more likely to be effective when the AF is <24 hours in duration or in patients with idiopathic AF.
