Hi Ron-
Joe is bothered by hot weather also, but he has always been bothered by hot weather. He has trouble breathing when it really gets hot. Prior to his last mitral valve surgery he was sweating profusely much of the time, even when it wasn't that hot.
Our house is not air-conditioned since we have a lot of trees and live in the Northeast, so we have fans going everywhere. I'm sure if we lived in a hot climate he would have lots of problems.
We haven't noticed any changes since the implant of the pacemaker, if anything, it helped and quite a bit too. He was in a-fib and the combination of calcium channel blockers with his pacemaker has regulated his rhythm, at least most of the time.
The last pacemaker check showed lots of activity on the printout, so I guess it's working its little head off.
By the way, he is also bothered by cold weather.
How does your intolerance for heat manifest itself? And what does the cardiologist say about it?
