Optimization of Initial Energy for Cardioversion of Atrial Fibrillation With Biphasic Shocks

Overview

Use of higher energy doses (120-150 J) may not offer additional benefits and higher success rate compared with low to moderate initial energy (100-120 J) of biphasic shock for atrial fibrillation cardioversion. In this prospective open-label randomized trial consecutive patients with AF and candidate to AF electrical cardioversion will be randomized to receive 100J or 120 J as initial dose of biphasic shock. Patients will be also randomized in each group to anterolateral or postero-anteriore placement of defibrillator electrodes.

Open-label randomized trial to assess the efficacy of alternative initial biphasic shocks (100 versus 120 J) for cardioversion of atrial fibrillation including alternative option for electrode placement (anterolateral or postero-anterior in each group).
