Just curious what was the underlying cause of your myocarditis? That is heart muscle disease destroying myocytes (heart cells). Was the condition due to bacteria, virus? Apparently, there was no permanent damage as your heart is pumping within a normal range.
Well they certainly ran the full gambit of tests on you to rule out the heart issues and did all the right tests it seems.....if it were me i would probably get a referral to a pulmonary doc and see if they spot anything...i am sort of at a loss here however the SOB, dizziness could point to not enough 02 saturating the lung functions if the heart docs have determined its not heart related....if your primary is at a loss with this and the heart doc rules everything heart related out try to remember that the lungs and heart are a team in our bodies....it won't hurt to give it a shot so that you can put this to rest and move on with your life................good luck and please let all of us know what this ends up to be....i am super curious............
