Abstract

BACKGROUND: Atrial fibrillation (AF) burden is associated with adverse outcomes; in some patients, very low AF burden may not be actionable. OBJECTIVE: This study aimed to model AF burden as a function of monitoring time without AF. METHODS: We included 11,639 US patients (median age 62 years [interquartile range 46‒73], 40.6% male) without permanent/persistent AF, monitored for ≥14 days in 2021 with the PocketECG device (MEDICALgorithmics). The overall 14-day AF burden was modeled as a function of monitoring duration without AF episodes lasting ≥30 seconds to
