Thank you so much for all the pixiedust and prayers. I just LOVE my doctor (he is the director of sports medicine -- I think that is his title -- at the university and only works in this medical office 2 nights a week, and is just the perfect doctor for me). I told him I had a primary concern (breathing/breathlessness issues) and secondary (vtach) and though I knew he'd be more concerned about the second, I really wanted to talk about the first.
When I acknowledged how far I have to go weight-wise and that that could be the reason I run out of breath when I jog, he praised me for how far I've come -- 65 pounds since 11/04 and going from totally sedentary to physically active 4-5x/week). I thanked him with tears in my eyes. Then, he asked if we've created a monster and couldn't I be content with walking. I told him that if that is an inherent physical limitation, then "yes", but if it is resolvable, then let's resolve it. He is pretty certain that while I may have exercised-induced athsma, it is more likely that the really heavy-duty drugs I took for ten years may have had a negative impact on my lung, perhaps even creating scar tissue -- beta blockers, calcium channel blockers, amiodarone.
Long story short (sorry, I do tend to go on, don't I?) -- He gave me an inhaler to use morning and night of azmacort (sp?) as a prophylactic but is sending me to a pulmonologist for a pulmonary function test.
On the heart thing -- I am going to let my treating cardiology team here in Delaware know that the vtach has re-started, but we'll all just be hypervigilant to be sure it doesn't start sustaining. I am not going to contact the doctor at Johns Hopkins unless and until it sustains because I really don't want to go down there for testing or evaluation until necessary. Because it is so intermittent right now and random and not related to exercise, I'm allowed to continue my training and we'll re-evaluate after the marathon.
So, thank you so much, guys, for your support. I really, really appreciate you all so much!
