The success rate of electrical cardioversion is higher than 95%. Factors to consider include synchronization of shocks to R waves, adequate sedation, and electrode position (apex anterior, apex posterior, or anteroposterior). Atrial flutter generally requires less energy for conversion than atrial fibrillation does; as little as 50 J may be necessary.
