AF Burden:<\/span><\/div>\n<div><span> \u2022 Median AF burden (first year): 0.07%.<\/span><\/div>\n<div><span> \u2022 First week: 3.65%; days 8\u201330: 0.04%; days 31\u2013365: 0%.<\/span><\/div>\n<div><span> \u2022 Median episode duration: 6 minutes; median onset time: 3.3 days.<\/span><\/div>\n<div><span> 4.
