The watchOS 8.3 and iOS 15.2 release candidates, released to developers this week, enables ECG functionality for Apple Watch users in China following regulatory approval for the feature over the summer, according to ITHome.
ECG capabilities, available with the Apple Watch Series 4 and later, allow users to quickly take an ECG by simply placing their finger on the Digital Crown and staying still for 30 seconds. Before the feature launches in countries, Apple must retain regulatory approval from the country’s respective and appropriate authorities. The feature first launched in the U.S. in 2018 with the Apple Watch Series 4, following FDA approval.
