Waking up same time overnight

I had pacemaker December 2019. Most nights I wake up around four and sometimes other times. Prior to my surgery cardiologist said my heart was stopping around 4. Is it likely I am waking up because it is kicking in or physiological   Just wish I could sleep


thank you


Sleep study ?

Brains, I see you are in the U.K.   I would ask your GP for a sleep study to help identify the problem since I see this has been going on for some time even before your pacemaker.  A Sleep consultant would help to identify the problem since there are several sleep disorders and causes for waking up at night.  Medication like beta blockers can also adversely affect quality of sleep too but so can many things which is why an in hospital sleep study can be helpful.  In the meantime going to bed at the same time and getting up at the same time each day will help

Sleep apnea in somewhat common for us, by all means get a sleep study.

PM recalibration and self-check

Most likely your PM is set to run it's self-check at 4 AM. Check with your device clinic and have it moved to a time you would find more convenient.

Of course there could be other reasons.

Hi, i had sleep apnea and went for a sleep study. Unfortunetly, i didnt qualify but most people i have talked to say a cpap machine has helped them tremendously. They rate you from 1-10 and i was a 6, whish was on the fence.  I am still going to keep trying. good luck.

I'm with AR_VIN, it might be the device doing a self check/recalibration.  Mine used to do it at 12:30am every night.  When I ask my "team" about it I was told it's not the device and it's just in my head and that I should just get used to it.  After 2 weeks more I called Medtronic and found out that it does a recalibration every night and that it was a "feature" that could be turned off by my EP.  I called the EP again and they tried again to tell me it wasn't the device until I told them that I had called Medtronic, then they said they would have to check on that.  3 days later or so they called me back to come in so they could turn that "feature" off.  I HATE being lied to, especially by people you need to trust with your life!

I finished 29th in London in 2 hours 20 minutes 30 seconds which is my fastest with or without a device so clearly it didn’t slow me down ! I had no problems apart from some slight chaffing on my scar - more Vaseline next time.
