After receiving the green light from South Korea's drug safety agency, Samsung is now rolling out its blood pressure monitor feature to the Galaxy Watch Active 2 via a firmware update. The move means the smartwatch can now keep track of its wearer's heart rhythm via its ECG sensor and blood pressure. But it's currently limited to the said country. While it might not be available here, this update gives us a glimpse of what the Galaxy Watch Active 2 can do.
To get this feature to work, the wearer needs to calibrate with the watch with a traditional cuff-style blood pressure monitor. Afterwards, the smartwatch uses pulse wave analysis to keep track of the wearer's blood pressure. Calibration needs to be done every four weeks to ensure accuracy. The readings will be synced to the watch's accompanying Samsung Health app, where users can track their data over days, weeks, and months. The information can then be shared directly with their healthcare provider if they want.
