Abstract 15336: Real-world Diagnostic Performance of Single-lead Handheld Electrocardiograms for Atrial Fibrillation Screening: The Vital-af Trial

Introduction: AF screening can detect undiagnosed AF, but concerns exist regarding false positives and downstream consequences. AF screening using single-lead handheld electrocardiograms (1L ECGs) is feasible, but diagnostic performance in a pragmatic screening setting is not well-understood. Methods: VITAL-AF is a cluster-randomized trial (NCT035115057) of population-based AF screening with 30-second 1L ECGs. Individuals aged ≥65 years...
