Apple’s latest-generation Apple Watch doesn’t just have a curved display and a new industrial design, one of the major features of the Watch when it launched last year were its advanced health-tracking capabilities, particularly in regards to heart health and AFib detection.

Those features arrived in the US in December, but users abroad have had to wait. Today, Apple announced that the electro-cardiogram feature and irregular rhythm detection functionality is coming to 19 European countries and Hong Kong in the Watch’s latest update. These users will also gain access to the irregular rhythm detection features available on Watch models Series 1 and later.
