What is the ECG app for Apple Watch?
With the ECG app on Apple Watch Series 4 or later, you can take an ECG similar to a single-lead electrocardiogram. The ECG app can record your heartbeat and rhythm using the electrical heart sensor on Apple Watch Series 4 and then check for signs of atrial fibrillation (AFib), a form of irregular rhythm.
Why is the ECG app not on my Apple Watch?
If the ECG is actually supported on both your Apple Watch and region, but you still can’t find it, there is always the option of installing/reinstalling it from the App Store. Search for ECG app or EGC Utilities. You must scroll down (sometimes a lot!) to find it.

Can Apple Watch detect heart palpitations?
