Relationship of Resting Heart Rate to Incident Atrial Fibrillation (From ARIC [Atherosclerosis Risk in Communities] Study)

The evidence on the association between resting heart rate (HR) and incident atrial fibrillation (AF) is conflicting. Whether change in resting HR is associated with incident AF is unknown. We evaluated 11,545 participants (mean ( ±SD) age: 57 ± 5.7 years) free of AF at baseline (1990-1992). Resting HR was obtained from 10-second electrocardiograms at baseline and 3 years later. AF diagnosis was ascertained from visit electrocardiograms, hospital discharge records, and death certificates through 2013.
