Over the summer, Apple made a huge splash when it announced the Apple Watch Series 4 would be the first over-the-counter device to offer ECG readings. With this week’s update to watchOS 5.1.2., the feature is finally available for Series 4 owners to try. Here’s how to use it.
According to Apple, the new feature is capable of detecting signs of atrial fibrillation, a serious form of irregular heart rhythm. The feature is only available to Apple Watch users in the US.
- Update your Watch and iPhone to the latest software
- Head into the iPhone’s Health app and set up ECG by following the prompts
TAKE AN ECG
- Tap the ECG app
- Ensure your Apple Watch is snug on your wrist
- Place your finger on the watch’s Digital Crown for 30 seconds
- Once the countdown is done, lift your finger off the Digital Crown
Once that process is complete, the Health app will display your results. If you have a sinus rhythm, it means your heart is beating in a uniform pattern. An AFib result means your heart is beating in an irregular pattern.
Apple says that the ECG app cannot detect a heart attack, blood clots, stroke, or other heart-related conditions. If you do get a result that’s concerning, talk with your doctor.
