One UI 5 Watch: Irregular Heart Rhythm Notification feature coming summer

Today, Samsung announced that Galaxy smartwatches running One UI 5 Watch will receive the Irregular Heart Rhythm Notification this summer. The feature will debut with the Galaxy Watch 6 lineup next month and will expand to Watch 4 and Watch 5 with the One UI 5 Watch update.

Combined with the app’s BP (Blood Pressure) and ECG (Electrocardiogram) monitoring, the One UI 5 Watch Irregular Heart Rhythm Notification feature detects heart rhythms suggestive of AFib (atrial fibrillation), 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 Rate monitoring, users can gain even deeper insights into their cardiovascular health.

Since its launch in 2020, Samsung Health Monitor app has expanded to 74 markets. 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.
