Apple Watch Alerted Runner to Serious Heart Problem

In a new ad shared on its YouTube channel today, Apple highlighted how the Apple Watch alerted an athlete named Connor to signs of atrial fibrillation. Apple said doctors later uncovered that Connor had a congenital heart condition, which resulted in him having open-heart surgery, so the Apple Watch potentially saved his life.


After noticing he had a very fast heart rate while training for a triathlon, Connor used the ECG app on his Apple Watch, which detected signs of atrial fibrillation.

The ECG app comes preinstalled on the Apple Watch Series 4 and newer and all Apple Watch Ultra models, but it is not available on any Apple Watch SE models.
