The update will enable ECG functionality on the Apple Watch Series 4 which was heavily publicized by Apple during the unveiling of the wearable.

Officially, the ECG feature of the Apple Watch Series 4 will only be available in the United States. The update also brings the irregular heart rate notification feature to all previous models, including the Apple Watch Series 1. The study found the ECG app on Apple Watch demonstrated 98.3 percent sensitivity in classifying AFib and 99.6 percent specificity in classifying sinus rhythm in classifiable recordings.

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".

This electrode pairs with another electrode built into the bottom of the Series 4's new sapphire crystal back. Current data shows that anywhere from 2.7 to 6.1 million Americans may suffer atrial fibrillation - a statistic that can be lowered and much more accurately measured with real-time, on-the-go ECG readings. AFib, if left untreated, is one of the leading conditions that can result in stroke, the second-most common cause of death around the world, Apple explains.

Both the ECG app and irregular heart rhythm notifications have received the De Novo classification from the Food and Drug Administration (FDA) in the U.S. Apple says it has been working for a number of years to obtain this, and no other smartwatch offers the same.

It was recently revealed that the Apple Watch Series 4's groundbreaking electrocardiogram (ECG) feature will be activated in the upcoming WatchOS 5.1.2 update. But if you want to share it with your physician, Apple makes it easy to export it all into a PDF.

Excitement had been building for the release of the latest version of the watch's OS once it became clear that Apple had begun circulating a training document giving key instructions on how Apple Store employees should interact with customers regarding the addition, so it was thought to be only a matter of time before watchOS 5.1.2 was released.
