Samsung Electronics today announced that the Irregular Heart Rhythm Notification (IHRN) feature1 on the Samsung Health Monitor app2 will soon be available in 13 markets starting this summer. Combined with the app’s Blood Pressure3 and Electrocardiogram (ECG)4 monitoring, the IHRN feature detects heart rhythms suggestive of atrial fibrillation (AFib), helping Galaxy Watch users understand their heart health more comprehensively.

The IHRN feature has been approved by the Korean Ministry of Food and Drug Safety (MFDS) last week, following recent clearance by the U.S. Food and Drug Administration (FDA). It will also be introduced in Argentina, Azerbaijan, Costa Rica, Dominican Republic, Ecuador, Georgia, Guatemala, Hong Kong, Indonesia, Panama, UAE, as well as Korea and the U.S., taking the total to 13 markets.

Alongside the on-demand ECG tracking, the IHRN feature checks for irregular heart rhythms in the background and warns the user of potential AFib activity. Together with the existing Blood Pressure and Heart Rate5 monitoring, users can gain even deeper insights into their cardiovascular health.

Since the launch in 2020, the Samsung Health Monitor app has expanded to 74 markets6 across the globe. Over 15 million Galaxy Watch users have kept track of their blood pressure and ECG right from their wrist, gaining a better picture of their heart health by continuously monitoring and recording their blood pressure and heart rhythms.

“Cardiovascular disease remains one of the main causes of death around the world, and we’re committed to empowering our users to stay informed about their heart health by providing monitoring tools, including blood pressure measurement and irregular heart rhythm notification,” said Hon Pak, Vice President and Head of Digital Health Team, MX Business at Samsung Electronics. “We’re constantly exploring new ways to help Galaxy Watch users obtain deeper insights on their health and wellness effortlessly, day and night.”

The Irregular Heart Rhythm Notification feature will first be available on the upcoming Galaxy Watch devices later this year, as part of the new One UI 5 Watch and later expanded to previous editions.7

2 Availability may vary by market or device. Due to market restrictions in obtaining approval/registration as a Software as a Medical Device (SaMD), it only works on watches and smartphones purchased in the markets where service is currently available (however, service may be restricted when users travel to non-service markets). This app can only be used for measuring in ages 22 and over.
