Acute AF termination includes termination to AT or sinus rhythm and is presented as ratio. Number of localized drivers, procedure duration, fluoroscopy duration, and RF duration are presented as mean±SD when available. AF indicates atrial fibrillation; AT, atrial tachycardia; PVI, pulmonary vein isolation; and RF, radiofrequency. Study by Atienza et al

^†is represented in 3 rows; study by Narayan et al,

^*Lin et al,

^‡and Seitz et al,

^§is represented in 2 rows to show baseline information in each arm (ie, driver+PVI, driver only, and control).
