Welcome to the Fitbit Community, @ismaeljo.
Regarding the inquiry in your post, the ECG feature is reliant on each country regulatory committee and Fitbit needs to have the approval to use it in that country. So it might be that Fitbit have applied for approval, but it has yet to be given. You can find additional information on our website at https://www.fitbit.com/global/us/technology/ecg
See you around.
