It's great to have you here @1191986! The Fitbit's radio operates at the 2.4GHz frequency, and uses lower power levels than Bluetooth. It is certified by the FCC, and many individuals with pacemakers do use our trackers.
Fitbit hasn't extensively tested these devices with pacemakers, and cannot cannot guarantee that there will be no interference or ill effects. You should consult with your doctor or other medical professional for an authoritative answer.
Regarding your question about the inaccuracies that you're having, please reply to the following questions:
- Are you seeing any difference in your step count or other information that's being tracked by your Blaze?
- Have you always used your Fitbit and pacemaker at the same time?
Keep me posted.
