GoKawiilCNET reporter's Apple Watch ECG test flags real heart irregularity during hospital comparison
A CNET journalist testing the Apple Watch Series 4's ECG feature against a hospital-grade electrocardiogram unexpectedly had the device flag an irregular heartbeat in his own heart, matching the hospital's findings. Doctors later determined the anomaly was benign, likely caused by stress and sleep deprivation, but the moment shifted his view of the watch from a novelty gadget to a legitimate health tool. He later gave Apple Watches to his parents, and one flagged an issue that led to his father's diagnosis and treatment for a serious heart condition.
