Roger that!! Good thought! I will act all dumb (which I am naturally good at) and ask the doctor to give me a short course in what all the wonderings of the line means. See what he says. I happen to have an EKG from my physical taken at a private hospital the other day. I don't suppose you or someone else here can read a EKG can you? My chest x-ray and ultra sound indicate a enlarged heart, so that is why I need to have a cardilogist look at me. Appreciate the tip!
