With the EKG app on Apple Watch Series 4 and later, you can check your heart for a condition called atrial fibrillation (AFib) where it beats irregularly. It works like an electrocardiogram (an EKG) that you would find in a doctor’s office.
Due to global regulation of medical devices, the EKG app is not available in all areas. And where it̵
Note: The EKG app cannot detect heart attacks. Contact your doctor if you experience any of its symptoms.
What is the difference between version 1 and version 2?
Version 1 and Version 2 of the ECG app are similar, although there are a few differences:
- Version 2 can monitor AFib when your heart rate is between 50 and 150 beats per minute. Version 1 can only check AFib if your heart rate is between 50 and 120 beats per minute.
- Version 2 adds a “Bad Recording” rating for when an EKG reading is unclear because you have moved, the watch is incorrectly positioned, or some other similar reason. Version 1 just has “Inconclusive,” which packs everything from heart conditions that the EKG app isn’t designed to detect to wearing your watch on the wrong wrist.
- Version 2 has an improved, more accurate algorithm.

How to check what version you have
Presumably Apple plans to roll out the ECG version 2 everywhere if it can. In the US, it launched with watchOS 7.2.
To check what version your watch currently has, open the Settings app and tap “Heart” then “EKG”.
You can also check it with your iPhone. Open the Health app and go to Browse> Heart> Electrocardiograms (EKG).
Tap “About” at the bottom of the EKG screen. The version appears under the Apple Watch heading to the right of Feature Version.
