Apple Watch ECG: Smart heart tracking feature arrives in UK

Apple Watch users across Europe can now measure their heart health after Apple turned on one of the smart watch's headline new features. After being regulatory approval, the company has flipped the switch that means the watch can take electrocardiogram, or ECG, readings. The update will arrive for anyone who has the latest watch as well as being updated to the most recent version of the software. While the technology to power the ECG feature has been present in all Series 4 Watches since they were released, Apple hasn't been able to turn it on because it has not been approved. That means a new update will be able to switch it on, without any extra work from owners.
