Image result for Apple Watch Series 4Apple declared the heart features in September, but didn’t make them available until Thursday with watchOS5.1.2. The new features are granted clearance from the US Food and Drug Administration and therefore are for US customers only.

The watch can properly check the wearer’s heart rhythm in the background and also send a notification if it detects irregular heart rhythm. That may point to atrial fibrillation, a condition that could increase the risk of stroke and other complications. Apple claims that the watch will inform users if it finds an irregular rhythm on five checks over at least 65 minutes.

When symptoms appear, users may also choose an EKG, or electrocardiogram, and share that with doctors. This attribute is available for the newest, Series 4 variant of this watch. The program, known as ECG, comes as part of a free software upgrade for the opinion, which also brings fresh Infograph complications for Mail, Maps, Messages, Locate My Friends, Home, News, Phone, Remote programs.

The irregular heart notification is available for older models, too, beginning with all the”Series 1″ model in 2016. It does not work together with the original, 2015 version.

Apple is incorporating medical characteristics to make the watch feel much more useful to individuals. A fall detection attribute started in September. It claims to have the ability to discern the difference between a trip and a collapse — and if the latter happens, it is going to propose calling 911 (or the equivalent outside the US). If it receives no response within a minute, the watch will automatically place an emergency call and message friends and family designated as emergency contacts.
