Your Apple Watch can be the key to preventing strokes in the future. Unlike traditional monitoring, wearables provide continuous heart tracking, allowing early identification of irregular heartbeats even before symptoms appear. Half of the participants wore an Apple Watch for 12 hours a day over six months, while the rest received standard care. Using photoplethysmography (PPG) and built-in single-lead ECG sensors, the Apple Watch offered real-time heart monitoring. Patients used the Apple Watch to record clinical-grade ECGs at home, helping doctors catch A-fib symptoms early.
