I had a pacemaker replacement 9months ago. most days i feel extremely tired often bedding a sleep during the day.i am paced at 60?

Recheck: Feeling tired could be due to lab abnormality or intolerance of the current heart rate. Either way, I would check with your cardiologist, he might make some changes that will make you feel better

Not the pacemaker: A heart rate of 60 is fine, and if there were issues it is easy to have checked for arrhythmia's. There could be many issues, would see your doctor.

Doctor assessment: May not be the pacemaker, although your doctor may have a mechanism for having the rhythm recordings fixed. There are a variety of other possible medical disorders that can present with excessive sleepiness. Further assessment and examination and maybe tests are needed to sort out. Suggest see your doctor.
