Charge 6 - AFib alert

[Jbondfl]

Has anyone else successfully use d the AFIB feature on this device where it actually notified you of AFIB event? I've had two high events, one last night. I was 170 BPM Resting heart rate and the device never noted it or recognized it. I had a previous event that my heart rate went up to 149 BPM and again, no alert or notification of that event. I don't get it. Any help would be welcome

Hello @Jbondfl 

This help page explains how Fitbits detects AFib and how the notifications work (<-- click link). 

Basically, Fitbit can only analyze your heart rhythm data for AFib when you’re still. If I remember correctly, the device is monitoring for high heart rate when you're still for at least 10 minutes.

@Jbondfl   I participated in the Fitbit Heart Study that developed this feature.  Fitbit published the results in the journal Circulation. Your Fitbit must detect an irregular rhythm for a minimum of 30 minutes in order to generate an alert.
