Currently, the usual initial strategy for direct current cardioversion (DCCV) typically involves delivering 200J of electricity between two pads placed in the anterior and posterior positions (i.e., one on the chest and one on the back). However, this technique may be less likely to result in successful cardioversion in obese patients (BMI ≥30 kg/m2). Failure to achieve sinus rhythm then necessitates additional shocks, which still may ultimately fail to terminate the patient's atrial fibrillation, thereby increasing the likelihood of adverse events from multiple cardioversion attempts "Dual-DCCV" is a technique in which four pads are used to deliver two simultaneous shocks of 200J, totaling 400J. Guidelines published by the American Heart Association/American College of Cardiology/Heart Rhythm Society and the European Society of Cardiology provide only general guidance regarding the appropriate technique and energy selection in patients undergoing cardioversion, with no specific recommendations pertaining to dual-DCCV or obese patients. This study aims to assess the safety and efficacy of dual-DCCV as an initial treatment strategy, compared to standard single-DCCV, in the obese population.
