BREAKING: ECG support for Galaxy Watch 2, Watch 3 rolling out to 31 markets

The full list of countries includes Austria, Belgium, Bulgaria, Chile, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Indonesia, Ireland, Italy, Latvia, Lithuania, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, the UAE, and the United Kingdom.

The Samsung Health Monitor app, which makes blood pressure and ECG measurement possible, is now available for download from the Galaxy Store in those markets. If you own either watch, you will also have to download a software update before you can start using the app. The update is rolling out now and you should be notified once it's available for your watch, but if you want to hurry things up, you can manually check for the update from the Galaxy Wearable app.

Blood pressure monitoring needs calibration for more accurate measurement

Also, to start monitoring blood pressure, you will need to calibrate your Galaxy Watch Active 2 / Galaxy Watch 3 with a dedicated blood pressure monitor. The process involves measuring your blood pressure with both the watch and the blood pressure monitor three times and putting in the values you get from the latter into the Samsung Health Monitor app. Of course, you could skip this step by adding in the values yourself without using an actual monitor, but that would make the results from the watch rather useless and inaccurate.
