Inconclusive ECG results on Charge 5

[marcopolo123]

Just bought a Charge 5 today specifically for the ECG, so I'm very disappointed that it keeps telling me that it can't read it when my HR is >120. It says mine is ~160 when the actual HR on the device shows ~70.

Welcome to the Fitbit Community forums, @marcopolo123.  

Thank you for sharing this information about the issue you're experiencing with your Charge 5

Before considering other options, may I know if the Fitbit app is updated? Is your Charge 5 syncing correctly? Have you also completed the Heart Rhythm Assessment on the Fitbit app? In the meantime, please give a try to the following steps:

1. Uninstall the ECG app from your Charge 5.
2. Force quit the Fitbit app and restart your tracker.
3. Open the Fitbit app and pull down on the screen to force a manual sync.
4. Install the ECG app one more time and make sure the permissions are enabled.
5. Tap Discover > Assessments & Reports > Heart Rhythm Assessment to double check if still appears completed 
6. Try taking a reading one more time and let me know how it goes.

Hope this helps, I'll be around.
