Apple Watch’s New Heart-Monitoring Functions Triggers Health Debate

Apple Inc. took a big step toward turning its smartwatch into a medical device, adding new heart-monitoring and fall-detection applications that doctors say could help detect serious medical conditions but also trigger false alarms and unnecessary medical care. The new additions, which Apple revealed Wednesday, are a prominent example of Silicon Valley’s moves into medical monitoring. The latest version of the Apple Watch is equipped with electrodes and sensors that turns it into an electrocardiogram able to measure a heart’s electrical activity and detect potentially dangerous disorders.
