I have left bundle branch block which I have thought to be asymptomatic for me. However, I have become heat intolerant, sweating profusely and yet still overheating. Is there a connection?

I have not seen a LBBB occurring specifically related to heat intolerance. There are several causes, though, that Cardiostar outlines below. In some cases, we don't find a cause, and after some initial cardiac evaluation often don't do anything further.
