Samsung Galaxy Watch5 update Afib

Samsung today announced that the Irregular Heart Rhythm Notification (IHRN) feature of the Samsung Health Monitor app has received FDA clearance. This feature will be shipping as part of the upcoming Samsung Galaxy Watch allowing users to proactively monitor heart rhythms suggestive of atrial fibrillation (AFib). Samsung will also be shipping this feature to existing Galaxy Watch4 and Galaxy Watch5 devices later this year.

This new feature in Galaxy Watch allows users to better understand their heart health using the Samsung BioActive Sensor, including on-demand ECG recording and HR Alert function that detects abnormally high or low heart rates.

“We’re excited to announce that Irregular Heart Rhythm Notification, designed to help millions of people around the world who may not be aware of a potential heart risk, has been cleared by the FDA,” said Hon Pak, Vice President and Head of the Digital Health Team, MX Business at Samsung Electronics.

Here’s how the feature will work:

  • Once activated in the Samsung Health Monitor app, the feature will check for irregular heart rhythms in the background via Galaxy Watch’s BioActive Sensor.
  • If a certain number of consecutive measurements are irregular, Galaxy Watch warns the user of potential AFib activity, prompting them to take an ECG using their watch for a more accurate measurement.
