AFib episodes not showing on Heart graph. Numbers very different

[NicoStein]

I've received AFib notifications for last night on my fitbit charge 6 but when i go to my Heart chart for the same time period it doesn't show anything odd. The numbers are very different. I'm wondering if there's something wrong with my Charge 6

@NicoStein   I don't think there is anything wrong with your Charge 6.  The daily heart rate graph shows an average heart rate over five minutes.  The Afib feature measures your heart rate on a beat to be basis.  The time stamp record in a notification shows time measured in milliseconds.  You can get a notification and your daily heart rate graph won't show a big difference.  Please contact your healthcare provider.  I participated in the Fitbit Heart Study agar developed this feature.  It is very accurate.
