Screening for atrial fibrillation: a narrative review

This review provides information about the current evidence-base for screening for atrial fibrillation (AF). The current burden of AF and recommendations related to AF screening are discussed, and randomised-controlled trial evidence for AF detection, clinical outcomes, harms and cost-effectiveness of population-based AF screening are reviewed. Finally, novel methods to refine the population to whom AF screening should be offered, which may improve clinical and cost-effectiveness, are considered.
