Digital recruitment and prevalence of screen-detected atrial fibrillation in nationwide patch-based ECG screening: the NORSCREEN randomized clinical trial
Authors' conclusion
The NORSCREEN trial demonstrates that fully digital, large-scale, site-less AF screening is feasible and effective in an at-risk population, identifying previously undiagnosed AF in 1.9% of screened individuals and showing high adherence to therapeutic recommendations.
