The Galaxy Watch Active2 was released in August of last year and finally receives the long-awaited ECG feature a year later. Unfortunately, this feature has only been cleared in South Korea - where Samsung's headquarters are.
Samsung was supposed to make ECG and fall detection available on the smartwatch as of Q1 2020. However, the date was pushed back. In May, the feature received clearance from MFDS - South Korea's regulatory service. Now, in August, the feature has been released in South Korea.
What does an ECG do? Great question. An electrocardiogram allows the user to monitor their heart rhythm to make sure it is healthy. If there is an irregularity detected, the user will get notified for either AFib (Atrial Fibrillation) or Sinus rhythm. An ECG measurement could take more than 30 seconds to take. If a result ends up incorrect, the smartwatch will show either Judgement failure or Signal Failure alters.
If the user ends up getting an ECG result that is unusual, Samsung says that that user should approach a certified health professional. To make assumptions based on the smartwatches readings could be dangerous.
Soon, we hope to see the ECG feature on both the Galaxy Watch Active2 and Galaxy Watch 3 in other markets.
