Lol well I did get my heart rate up to 215 bpm, it wasn't too fun my heart rate was at like 180 then I had a pvc and I panicked and it shot up to 200+...but im glad to hear that if there was something wrong they would have told me.
If they found anything significant or immediately dangerous, you would never have walked out of the office. You would have been put in the hospital on the spot. I really think you are going to find that everything is fine.
The test was "no big deal" was it??? See? You were worried :-)
