Sounds like you need a heart doctor who also races or is a serious bike rider/runner/etc. In 1982 to 1984 in the work up for the L.A. Olympics our cycling club, the LaJolla Cycling Club had several nationally ranked riders, one being Mark Gorski and as such we were lucky to have several specialist including a heart doctor who would monitor our training and how we did in races and training rides. I was followed since although a 35+ class rider, I had smoked for years and they wanted to see how my body was reacting to training and racing. During my track work outs I could get my heart rate to 200+ BPM for short periods but my B/P was staying high, 190/110 even though my resting pulse was 40 or so. They finally got me on meds that lowered the B/P to 145/85 on average and it stayed that way until I had a mini-stroke in Sept of 2013. Now it is 130/70 and the doctors are much happier.

I found that this is why it is called "practice medicine" as unless the doctor has a background in exercise then they are probably making educated guesses!
