Key result
Atrial fibrillation affects ~4% of older adults, with single-lead ECGs identifying newly diagnosed cases.
Cross-Sectional (n=22,616)
Yes
A simple 1-lead ECG screening in a general adult population identified a 3.9% overall prevalence of atrial fibrillation, with 0.3% being newly detected, supporting the feasibility of targeted screening strategies.
Supports targeted 1-lead ECG screening for AF in adults ≥45; leaves open outcome benefits pending prospective trials.
The findings highlight the increasing prevalence of AF with advancing age and its higher occurrence in men compared to women. The screening-detected prevalence of AF of 0.3% among participants in this general population study suggests that simple 1-lead ECG could be a manageable approach to screen for AF. The strong association between AF and cardiovascular comorbidities emphasizes the need for management strategies to address this condition, particularly in older adults.

Höiby et al. (2025) conducted a cross-sectional in Atrial fibrillation (n=22,616). Atrial fibrillation had an overall prevalence of 3.9% among Swedish adults aged 45 years and older, with 0.3% being newly diagnosed cases identified by a single 1-lead ECG.
