MacRumors Hands-On With the ECG Feature for Apple Watch Series 4
Apple has received de novo FDA clearance for the ECG feature in the Apple Watch Series 4, but FDA clearance is not the same as full FDA approval. The FDA does not recommend that the ECG feature be used by those under 22 or those who have already been diagnosed with atrial fibrillation.
The Apple Watch Series 4's ECG function is not designed to replace traditional methods of diagnosis or treatment, and Apple intends for it to be used for informational purposes.
At the current time, Apple Watch Series 4 owners in the United States are the only Apple Watch customers who can take an ECG because the feature needs regulatory approval to be made available in other countries. Apple is working to expand the feature to additional countries.
While the ability to take an ECG is limited to Apple Watch Series 4 users, Apple is implementing a secondary feature designed to send Apple Watch Series 1, 2, 3, and 4 users a notification if an irregular heartbeat is detected via the normal heart rate sensor in the device.
