Strange happenings shortly after going to bed
I am wondering if anyone has had anything like this. I did ask my cardiologist several years ago and he had no answer.
I'm 80 and function very well with a low ejection fraction following a massive MI six years ago. (No pacemaker or ICD)
This thing I am about to explain happens only occasionally as it did even before my heart attack.
Generally this happens very shortly after I have gone to sleep and I am awakened (enough to be aware) of something happening, sometimes with some slight chest awareness but with legs becoming very cold. Lasts probably less than a minute.
Once at least also my arms became cold. The coldness goes away as quickly as it happens.
My most recent experience was a few nights ago when I seemed to be having quick heart beats, but they were gentle, nothing like thumping.
I only ever asked the one doctor about this and it seems to me he should have known more. Perhaps I did not explain it well, though think I did. (I do have some suspicions.)
Any thoughts would be most welcome.
