Samsung's unreleased Galaxy Watch Active follow-up, the Galaxy Watch Active 2, will be the company's first smartwatch to feature an ECG heart rate tracker, Wareable . However, the report claims that the feature is not available at the time of the first release of the watch and will be added with an update after its release in the first half of 2020. At startup, the watch is expected to have a more basic heart rate tracking with alerts if your heating rate jumps too high or falls too low.
This is not the first time that a Samsung Smartwatch includes heart rate measurement. Earlier watches such as the Galaxy Watch Active and the Galaxy Watch, however, only contain less accurate optical trackers based on light. In contrast, electrocardiogram trackers (ECG trackers) measure more accurate electrical signals and also give them the ability to detect health conditions. However, according to the FDA, the ECG must grant approval for devices with this functionality. This is reportedly the reason for the delayed release of the feature by Samsung.
