AF episode duration
After calculation of the longest aggregate AF burden within 24 h per patient, 3404 (44.5%) patients had AF < 6 min, 1367 (17.9%) patients had AF 6 min–6 h, 1206 (15.8%) patients had AF 6–24 h, and 1674 (21.9%) patients had AF ≥ 24 h. This equated to 2880 (37.6%) patients having at least 6 h of AF within a 24-h period.
