Macrumors noted last week that Apple was already starting to train employees how to communicate relative to the latest version of the watch, with instructions that include making it clear the ECG app is regulated and only available in regions where it's been cleared for use.

ECG features are limited to Series 4 Watches, but Apple's irregular heart rhythm notification feature works on Series 1 devices and newer.

Per Macrumors, Apple has told store employees to let customers know that the ECG app is "not meant to be a diagnostic device or to replace traditional methods of diagnosis".


Apple on Thursday released watchOS version 5.1.2, a free update that enables one of the most compelling features on Apple Watch Series 4.

Apple expects it to change (and save) lives.

The ECG feature is created to "capturing heart rhythm in a moment when they experience symptoms like a rapid or skipped heart beat and helping to provide critical data to physicians", which could potentially save a lot of lives. When a user places their fingertip on the latter, it forms a circuit that allows the Watch to read their heart's rhythm in just 30 seconds.


Download watchOS 5.1.2 by going to the Software Update section of the General menu in the Watch iOS app.

"Apple Watch has helped so many people around the world, and we are humbled that it has become such an important part of our customers' lives", Jeff Williams, Apple's chief operating officer, said in a statement. After the test is complete, users can view results, complete with a chart of the heart rhythm, in the Apple Health app. But if you want to share it with your physician, Apple makes it easy to export it all into a PDF. Through normal heart rate tracking, Apple Watch Series 1 through Series 4 will also check for signs if irregular heart rhythm that could be related to AFib and alert you with a notification if it detects five irregular heartbeats across 65 minutes.

To enjoy these features on your Apple Watch, upgrade to watchOS 5.1.2 later today.
