Apple Watch ECG Feature Only Available in the United States

While this is nothing new, it is important to reiterate that the ECG feature on the Apple Watch Series 4 is only available to owners in the United States. This is because of regulations, and the Apple Watch has not been approved outside of the U.S. at this time. The reason to bring this up is because, as MacRumors has pointed out, changing your device's region to the United States will not affect this. Only models purchased in the United States will work with the ECG feature. Hopefully, other countries get this feature soon. This obviously isn't Apple's fault. It's just part of the process.
