The early detection of asymptomatic atrial fibrillation (AF) is considered essential for preventing thromboembolic events and the progression of heart failure. Numerous wearable devices have been developed to facilitate this objective. The authors employed stroke risk analysis (SRA), a method that stratifies the risk of paroxysmal AF through the evaluation of electrocardiogram data. This algorithm proved effective in screening patients with asymptomatic paroxysmal AF, with 29.4% of participants categorized as high-risk. Among these high-risk individuals, AF was detected in 38.7% following a 7-day screening period. Nevertheless, several critical concerns merit discussion.
