I finally had one 2 years ago and I wrote a thread about it. Having high blood pressure all my life and a lifelong runner/cyclist. It was scared to death my blood pressure was 1805/90 before the test even began. They were not going to let me do the test but dr said ok he does one everyday running or riding, So at 55 at the time they wanted my heart rate to go to 148 and it got there, they said my BP could go 250/110 and it was like 240/90 at 148 BPM. They stopped it and said I was ok and noticed I was not working too hard really. I guess I passed but that does not mean much, you really need an full scan but they did mine because my ekg had a change. The cardiologist did EKG and it did not show a change said I had a typical EKG of someone who does endurance type stuff.
