New research suggests that the Apple Watch is more effective at detecting atrial fibrillation than traditional methods, uncovering cases in people with no symptoms. A study of 437 high-risk individuals found 21 cases using the smartwatch, compared to 5 with standard care. Continuous monitoring with wearables could lead to earlier diagnosis and reduced stroke risk.

The study, published in the Journal of the American College of Cardiology, involved participants over 65 at risk of stroke. Those using the Apple Watch were monitored for six months, with 21 cases of AFib detected, 57% asymptomatic. Smartwatches with PPG and ECG functions could help doctors diagnose arrhythmias early, potentially reducing stroke risk and healthcare costs.

Presented at the European Society of Cardiology’s annual meeting, the study showed that the Apple Watch detected AFib in people who weren’t seeking medical help. Continuous monitoring with wearables can catch hidden cases missed by short-term tests. The findings suggest potential benefits for patients and the healthcare system, offsetting device costs.
