Choose Set Up ECG App on the pop-up telling you about the ECG app on Apple Watch. If the app detects an abnormal heart rhythm, it will tell them that it has detected atrial fibrillation and Apple will recommend seeing a doctor for professional help. With hundreds of millions of iPhones in pockets around the world and watches on tens of millions of wrists, Apple says it has a responsibility to empower people with more information about their health. It follows the release of iOS 12.1.1 yesterday that had everyone anticipating watchOS 5.1.2, which adds the ECG app to Series 4 models of the watch as well as irregular heartbeat notifications to older watch models.
Who can access the ECG app and irregular rhythm notification?
For Apple Watch Series 4 users this is an extremely important update since it unlocks the full potential of the ECG sensor which is limited to the United States for now.
With the ECG app rolling out today, Jeff Williams sat down for a brief interview with TIME where he called the ECG app a huge opportunity to improve lives. 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.
The Apple Watch will passively read your heart rate in the background and will warn you if it spots a suspicious pattern. Once the the Apple Watch is done taking the ECG measurement, it will show the user a heart rhythm classification which can be shared with their doctor. One of the standout features is the new heart-monitoring hardware that allows the device to take an electrocardiogram (ECG) to monitor electrical activity in the heart. Apple built electrodes into the watch's back crystal and digital crown (a.k.a. side dial).
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.
When measuring is complete, you'll see a reading on your Apple Watch face. The ECG results are stored on your iPhone in the Health app. "At the American Heart Association, we are committed to educating and empowering people to be proactive in all areas of their heart health and general well-being". The app also provides an option to export the test as a PDF to share with a physician.
