Samsung said it will activate ECG on the Galaxy Watch Active2 in Q3 2020, and the company has kept its promise as the feature is now enabled on the smartwatch, albeit in South Korea only.
To use the ECG feature, Galaxy Watch Active2 users need to download the Samsung Health Monitor app launched in June on the paired smartphone.

It provides Atrial Fibrillation results when your heart rate is higher than usual but shows Sinus rhythm when everything's normal.
