I'm a 31 year old male with high blood pressure, anxiety, and a few recorded PVCs. I recently had a stress test with some ST depressions, which the cardiologists suspected to be a false positive. Nonetheless, to be on the safe side I was given a nuclear stress test - everything turned out just fine, my cardiologist said my heart is perfectly normal. The only problem was the high heart rate - when I went to get on the treadmill my heart rate jumped from 90 bpm to 145 bpm.
