Doctor said my heart's size is on the upper end of normal. But nothing serious at all. He put me on new blood pressure meds. (diuretics aren't a endurance athlete's best friend.)
He did say that these things worry doctors. When everything comes back normal but the symptoms say something different. He kept wondering if he was overlooking something. I told him that I've been feeling better and that eased his mind a little. He seemed so concerned and really wanted to get to know about my training and abilities as an athlete.
Several times this month I sent recordings of my heart rate over the phone to his office. He showed me the results. It was weird - but normal he said. My HR went from 70bpm down to 50bpm within a second. He said someone like me can see this a lot.
My flutters have subsided. I don't get the pain in my left side like I use to. Sometimes my heart will beat hard but not all the time like before. I can also train on my upper limits without getting dizzy and pressure.
I want to thank you guys for your prayers and thoughts. I've had some serious fear these last couple of months - since the first EKG came back with signs of LVH. Maybe I can relax and sleep tonight without anxiety.
