Abstract

This retrospective cohort study aimed to compare the one-year outcomes of anterior–posterior (AP) and anterior— lateral (AL) methods of cardioversion for atrial fibrillation (AF). A total of 2168 patients were included, with 1125 patients in the AP cardioversion group (Group 1) and 1043 patients in the AL cardioversion group (Group 2). Baseline characteristics, primary and secondary outcomes, safety outcomes, and logistic regression predictors of sinus rhythm were analyzed. The results showed comparable rates of maintaining sinus rhythm at the one-year follow-up between the two groups (65.8% in Group 1 vs. 65.7% in Group 2, p = 0.042). There were no significant differences in the incidence of AF recurrence or safety outcomes between the groups. Logistic regression analysis identified the duration of AF and the presence of coronary artery disease as significant predictors of sinus rhythm maintenance. Additionally, the use of the AL method was associated with a higher likelihood of AF recurrence compared to the AP method (p = 0.043). These findings suggest that both the AP and AL methods of cardioversion are effective in achieving and maintaining sinus rhythm in AF patients. The duration of AF and the presence of coronary artery disease should be considered when selecting the cardioversion approach. These results contribute to the understanding of optimal treatment strategies for AF and support personalized management decisions based on individual patient characteristics.
