Every Apple Watch Heart Health Feature (And What They Do)

The Apple Watch has evolved into a significant tool for monitoring heart health, featuring several key functionalities designed to enhance user awareness and safety. It includes an optical heart sensor that measures heart rate, alerting users to unusually high or low rates which could indicate conditions like atrial fibrillation (AFib). The watch also offers an ECG app that can perform an electrocardiogram to check for signs of AFib, providing medical-grade results that can be shared with healthcare providers. Additionally, the irregular heart rhythm notification feature passively monitors for irregular heartbeats. For those engaging in physical activities, the watch tracks cardio fitness levels, warning users if their cardiovascular health might be below average. It also monitors for signs of potential heart issues during sleep, like low heart rate or irregular rhythms, and can detect falls, automatically calling emergency services if necessary. These features collectively make the Apple Watch a proactive device in managing and alerting users to potential heart health issues.
