Apple Watch has proven to be a lifesaver many times over for its owners but now it’s also being used to help save people that don’t even own one.

A physician in San Diego recently shared how he used the ECG on his Apple Watch Series 4 to detect atrial fibrillation in someone while chilling at a restaurant. And it probably saved the person’s life.

Dr. Tommy Korn shared his incredible experience on Twitter this morning showing a video of the diagnosis while he was at a restaurant. We’re not sure what sparked Korn to have the person test for A-fib. This might be the first publicly reported incident of Apple Watch’s ECG saving someone’s life even though they didn’t own one. It certainly won’t be the last though.

In the replies to his tweet, Korn indicated that the person diagnosed with A-fib is doing alright.

Episodes of A-fib often show no symptoms. Usually you have to go to a hospital to check if you have it. Dr. Korn is a ophthalmologist (eye doctor) which makes the entire incident all the more impressive.

If you own a Series 4 and lend it to a friend for a quick A-fib diagnosis you can go back and delete the recording after so it doesn’t mess with your own Health data.
