Apple Watch Series 4 ECG feature expected to roll out today but only in the US

The Apple Watch Series 4 is the biggest makeover in design and functionality for Apple's wearable which makes it a stellar fitness tracker and connected device. Apple Watch is also a health tracker and one that can monitor various aspects of a user's health and even detect falls. 

The Apple Watch 4 has an ECG function that can detect irregular heartbeat and while this is being rolled out only in the US there are a lot of caveats. As the first device to offer this, Apple Watch, while helpful, should not be the basis for clinical action. US Apple Watch users should expect to see the feature after receiving the WatchOS 5.1.2 update.
