WatchOS 5.1.2 is Available Today, Brings ECG and Irregular Heartbeat Detection


And while Apple did receive FDA clearance for the Series 4, it's a de novo classification.

Apple's ECG feature, which was introduced on its Watch Series 4, is finally set to land via a watchOS 5.1.2 software update.

Apple Watch Series 4 devices all have built-in electrodes that can measure electrocardiograms, or ECGs.

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. Among the features announced was a preview of the ability to generate an electrocardiogram or ECG within thirty seconds by placing a finger on the Digital Crown. 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. "With the release of these heart features, Apple Watch takes the next step in empowering people with more information about their health".

The reading will show you whether you have a normal sinus rhythm, or if there are signs of atrial fibrillation (AFib).

Researchers said the findings "provide new evidence of the impacts of climate change on Arctic melting and global sea level rise".

Officially, the ECG feature of the Apple Watch Series 4 will only be available in the United States. This means that the agency sees the ECG app as being of "low- to moderate-risk" to a user's health. Keep in mind that the download and installation may take a while so make sure you do not use your iPhone or Apple Watch while the wheels are in motion. The Health app even allows users to export their data as a PDF so they can more easily give it to their doctor.

One of the standout features of the Apple Watch Series 4 is its ability to execute an ECG (electrocardiogram).

While users have already been able to get notifications about irregular heart rhythms, the ECG will take things a step further.

Apple Watches running watchOS 5.1.2 can also detect irregular heart rhythms in the background and send out a notification if an irregular rhythm is detected. It's available for Series 1 devices and newer that are paired to iOS devices running iOS 12.1.1 and higher.
