Just a couple days after the release of iOS 12.2, Apple has released its Apple Watch companion update, watchOS 5.2. With it comes a bit of a surprise: support for the irregular heart rate detection and the ECG function on Apple Watch Series 4 for many European countries.
When Apple released the Apple Watch Series 4, it only promised the ECG function for the United States, stating that it had been cleared by the FDA to do so. Other countries would get the hardware, but would be locked out of the ECG software until Apple had secured the proper local clearances. Apple gave to timeframe for this, but it was commonly assumed that it could take a year or more.
