Samsung Brings Irregular Heart Rhythm Notification to Galaxy Watch in 13 Markets

New Irregular Heart Rhythm Notification feature added to existing ECG monitoring to help users track abnormal heart rhythms and gain deeper heart health insights

Samsung Electronics Co., Ltd. today announced that the Irregular Heart Rhythm Notification (IHRN) feature[1] on the Samsung Health Monitor app[2] will soon be available in 13 markets starting this summer. Combined with the app’s Electrocardiogram (ECG) [3] 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 Heart Rate[4] monitor, users can gain even deeper insights into their cardiovascular health.

Since the launch in 2020, the Samsung Health Monitor app has expanded to 74 markets[5] across the globe. Over 15 million Galaxy Watch users have kept track of their ECG right from their wrist, gaining a better picture of their heart health by continuously monitoring and recording their heart rhythm.

“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,” 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[6].

[1] The app intended for adults 22 years and older analyzes pulse rate data to identify episodes of irregular heart rhythms suggestive of AFib and provides a notification suggesting the user record an ECG to analyze the heart rhythm. The IHRN feature is not intended to provide a notification on every episode of irregular rhythm suggestive of AFib and the absence of a notification is not intended to indicate no disease process is present; rather the feature is intended to opportunistically acquire pulse rate data when the user is still and analyze the data when determined sufficient toward surfacing a notification

[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).

[3] The ECG app is not intended for users with known arrhythmias other than atrial fibrillation or users under 22 years old. Users should not interpret or take clinical action based on the device output without consultation of a qualified healthcare professional.  The ECG app is not intended to replace traditional methods of diagnosis or treatment.
