Atrial fibrillation (AF) is the most common heart rhythm disorder seen in clinical practice, with an estimated 2.7-6.1 million people in the U.S. affected by the disorder \[1\]. Previous studies have demonstrated that left atrial volume is a predictive measure of incident atrial fibrillation \[2\]. This study aims to add to the literature by investigating predictive measures of left atrial global longitudinal strain (LA GLS) that would be suggestive of maintenance of normal sinus rhythm post cardioversion. If the investigators could gain insight on the connection between LA GLS and cardioversion among patients with atrial fibrillation, the investigators could potentially help the clinical management of patients pre/post cardioversion, and potentially change poor outcomes.
