Summary

Wearable technologies are increasingly used to detect atrial fibrillation (AF) outside clinical settings. This review finds that continuous screening with wearables nearly tripled AF diagnoses in asymptomatic, high-risk individuals, leading to more treatment but no clear improvement in outcomes. The findings suggest overdiagnosis and emphasize the need for careful integration of wearable technologies in primary care.
