Galaxy Watch ECG

Samsung has added an ECG monitor to the Galaxy Watch 3 and Watch Active 2.


Samsung has finally added an ECG monitor to the Galaxy Watch 3 and Galaxy Watch Active 2, the tech company announced Wednesday. The FDA-approved electrocardiogram function is available as of Sept. 23 on the two wearables through the Samsung Health Monitor app when connected to a Galaxy phone.

The app on the Galaxy Watch 3 and Galaxy Watch Active 2 can monitor heart rhythms and spot irregularities and signs of atrial fibrillation, or AFib, a type of irregular heartbeat. 

Here's how to use the ECG monitor:

  1. Open the new Samsung Health Monitor app with your smartwatch on your wrist
  2. Sit down and rest your arm on a flat surface
  3. Press your fingertip on the top button
  4. The app will classify your ECG as either sinus rhythm or AFib
  5. You can then record things like fatigue or dizziness
  6. It can then send a PDF report to your health care provider

The Galaxy Watch 3 also now has oxygen saturation tracking and a digital running coach with real-time info on your pace and form and after-workout VO2 max reports.

The smartwatch announcements came as Samsung held yet another Unpacked event online Wednesday.
