Atrial fibrillation (AF) is the most common sustained arrhythmia in clinical practice, affecting slightly less than 1% of the general population.1 Patients with AF suffer from a decrease in functional capacity secondary to a combination of palpitations, dyspnea, myocardial ischemia, congestive heart failure and hypotension.2,3 In addition, unorganized atrial electrical and mechanical activity result in blood stasis and the formation of atrial thrombi placing the patient at risk of systemic thromboembolism.4 It is therefore important, if feasible, to attempt cardioversion (CV) to normal sinus rhythm (NSR) in these patients.
The most concerning complication of CV in AF is systemic thromboembolism, and more specifically stroke. In 1960, Goldman reported a 1.5% embolization event rate in 400 AF patients undergoing chemical CV who had not received anticoagulation.5 This study proposed for
