Functional heart block vs structural heart block
Today my doctor told me that I was having paradoxical responses to PM programming. He was extending my PR interval to reduce the incidence of atrial pacing. I told him I pace at rest, during exercise I go into NSR and stay there for a few minutes when finished. As my heart rate returns to rest I go into heart block.
He told me this is a functional block not a structural block which makes sense since my heart block is very intermittent. He also mentioned a catacholeme issue may be to blame. Has anyone had this problem worked up?
