I spoke with my cardiologist today and it was good news!! He spoke with his colleague in Tucson and the verdict is that the Tucson doctor doesn't think that I need to do any further testing because he doesn't think the abnormalities that are on the MRI look like ARVD. He recommends that I do another MRI in a year to recheck it. So, that's what I'm going to do for now! :-)
I'm just happy because now I can exercise without worrying about keeling over!
