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.
GoKawiil's interpretation of the reporting above, not reported fact.
The account illustrates how consumer wearables have moved from lifestyle accessories to genuine early-warning health tools, even with far fewer sensors than clinical equipment. It also underscores growing evidence that smartwatch health alerts can prompt medical intervention before symptoms become apparent, reinforcing the case for wider adoption among older or at-risk users.
- The Apple Watch Series 4's single-lead ECG matched a hospital's 12-lead ECG in detecting an irregular heartbeat.
- The flagged anomaly was benign but demonstrated the watch's ability to catch cardiac events before symptoms appear.
- A family member's Apple Watch later helped detect a serious heart condition, reinforcing real-world diagnostic value.
Apple Watch Series 9 — The Series 9 carries forward the same ECG app that flagged an irregular heartbeat in this story, letting you take a medical-grade single-lead reading right from your wrist. It's a great way to keep tabs on your heart health continuously, not just during doctor visits.
