How do I activate the Atrial Fibrillation feature?


Helo devices continuously monitor your Atrial Fibrillation (AFib) when you activate it.

  • On BioSense: 

1. Open the App and go to the Device page. 
2. Scroll down until you find 24h Atrial Fibrillation and click on it to switch it ON.

  • On Watch Generation 2 and Watch Lite SE:

1. Go to the Health page and scroll down until you find AFib, and click on it. 
2. Click on the switch displayed on the screen to activate the 24h Atrial Fibrillation. 

Please note: 
- This feature requires a Wellness+ subscription. 
- The result will be visible on the App only after 6 hours, as the watch will monitor and collect the atrial activity to set a baseline for more accurate results.
- The green optical sensor under the device will always be on when you activate Atrial Fibrillation (AFib) feature.
Does the Atrial Fibrillation need to be calibrated?
