Cumulative Frequency of Subclinical Atrial Fibrillation Detection Over up to 28 Days of Ambulatory ECG Monitoring, ARIC Study, 2016-2017, n=16

*Subclinical AF: Zio® XT Patch detected AF and no clinical (AF diagnosed based on prior ARIC ascertainment or self-reported no prior AF diagnosis on visit 6 ZIO questionnaire).

†Zio 1 (in solid gray) corresponds to subclinical AF detected on the first patch worn for ≤14 days. Zio 2 (in striped gray) corresponds to subclinical AF detected on the second patch worn for ≤14 days. Of the 16 participants with subclinical AF detected up to 28 days monitoring, 9 participants had AF on the first patch (56.3%). All cases were detected by day 21.

AF - atrial fibrillation; ECG - electrocardiographic; ARIC - Atherosclerosis Risk in Communities.
