Hello, I had a pacemaker installed three months ago and have appreciated reading information on this forum. My question is about use of a Fitbit to track sleep stages after having a pacemaker. I had tracked my sleep and sleep stages regularly using a Fitbit InspireHR device prior to the pacemaker. After getting the pacemaker my Fitbit device records little or no REM sleep. Deep sleep recorded is more variable than pre-pacemaker. I've therefore been trying to find out whether my sleep is actually suffering or whether sleep stages can no longer be accurately determined with a Fitbit? If the Fitbit is no longer accurate for sleep stages, are there other devices available that can record my sleep stages accurately?
I have had sleep difficulties for several years and tracking and improving my sleep has been an important measure of health for me. I'd really appreciate anyone's experience or advice on this. Thanks so much.
