ECG and Heart Health
There’s been no change from the Apple Watch Series 4 in the health monitoring features such as the ECG and irregular heart rhythm notifications, but if you still haven’t upgraded from a Series 3, you’re missing out on these important features that have already proven to save lives many times over.
Plus, while the ECG feature was restricted to the United States when the Apple Watch Series 4 first came out last year, it has since expanded to over 32 countries, including Canada, India, Hong Kong, Singapore, and almost all of Europe.
