What’s actually slowing this PC down?

No. The Galaxy Watch7 does not continuously scan for heart conditions or constantly monitor for atrial fibrillation (AFib). Samsung’s Irregular Heart Rhythm Notification (IHRN) checks the wearer’s pulse a few times a day while they are still; if it detects a qualifying irregular rhythm pattern, it can prompt them to record an ECG.
IHRN is informational, not a diagnosis, and it may miss episodes. A notification is not confirmation of AFib, and no notification does not rule out AFib or another heart condition.
How Galaxy Watch7 heart rhythm notifications work
Samsung’s IHRN feature uses pulse data collected by the watch’s BioActive Sensor to look for irregular rhythms suggestive of AFib. It operates in the background, but “background” does not mean continuous surveillance: Samsung says the watch checks a few times a day while the wearer is still, rather than constantly looking for AFib.
Samsung says a notification may follow one hour of detected irregular rhythm suggestive of AFib. The feature then prompts the user to take an ECG using the Samsung Health Monitor app. The pulse-based notification is a signal to follow the app’s instructions and consider appropriate clinical guidance, not a diagnosis.

What the feature can and cannot tell you
| Question | What IHRN means |
|---|---|
| Does it constantly monitor for AFib? | No. Samsung says it checks a few times a day while the wearer is still. |
| What does an alert indicate? | A pulse pattern suggestive of AFib was detected; the app may prompt the user to record an ECG. |
| Does an alert diagnose AFib? | No. It is informational and is not a substitute for evaluation by a healthcare professional. |
| Does no alert mean there is no AFib? | No. The feature may not notify for every episode, including episodes lasting less than one hour. No alert does not rule out disease. |
The FDA’s indication for the Samsung ECG Monitor Application with IHRN describes an over-the-counter software medical application for informational use in adults 22 and older. It analyzes pulse-rate data to identify episodes of irregular rhythms suggestive of AFib and prompts the user to record an ECG. The FDA indication also states that it is not intended to notify on every episode.
Galaxy Watch7 compatibility and availability
Samsung lists Galaxy Watch7 as a supported watch for Samsung Health Monitor. Using IHRN requires the app on the watch and phone, a compatible Galaxy smartphone, and the relevant software. Availability may vary by market, carrier, watch model, and paired phone, so check Samsung’s current local guidance and your device configuration before setup.

- Next-Generation 3nm Processor: Exynos W1000 chipset delivers significantly faster performance and smoother app navigation.
Supported hardware does not guarantee that the feature is available or enabled for every user. Samsung’s earlier 13-market rollout announcement describes the launch at that time, not the current global availability list.
How to check and respond to an IHRN notification
- Check Samsung’s current Health Monitor instructions for your country and confirm that your watch and paired phone meet the requirements.
- If IHRN sends a notification, follow the instructions in Samsung Health Monitor, which may prompt you to record an ECG.
- Discuss the notification and any symptoms with a qualified healthcare professional. Do not use the watch’s result alone to make clinical decisions.
- If you have concerning symptoms, seek appropriate medical care even if the watch has not sent a notification.
