How does the ECG app work on Sense?

[mgrosvenor]

Hi, 

I've just started using my Fitbit Sense, and wanted to know how the ECG-Atrial Fibrilation monitor works.

Is it automatic or is it part of the 2-minutes EDA scan process?

Thanks

Welcome to the Sense community.To the best of my knowledge the A-Fib monitoring is automatic if you enable it in the FitBit app on your phone, there is an option to turn on in the phone app. ECG is not automatic. You start an ECG using the ECG app on your watch, swipe to the right a few times and you should see the icon, Tap that and follow the on screen instructions.

Hi @mgrosvenor   Your Sense has two features that help you monitor for atrial fibrillation.

• The ECG app uses hardware in the Sense to record a 30 second Lead I ECG.  Fitbit's Help article: What is the Fitbit ECG app? 
• The Irregular Rhythm Notifications use the optical heart rate monitor and are available on many devices.  Fitbit's Help article: How do Fitbit Irregular Rhythm Notifications check for atrial fibrillation (Afib)? 

The EDA scan is a different monitor.  EDA stands for electrodermal activity and is one of Fitbit's stress management features.
