I agree the treadmill test is much harder physically than nuclear test where you are usually sitting.

I think what the original posters and even I were referring to was not know what the symptoms of the nuclear test would be and then having one. It scared me to death as the pounding of my heart was very traumatic. I wish the cardiologist would have explained the test in depth and what it would feel like beofre I had it.

The nuclear test I had was at a private office of the cardiologist. It was before I became a patient at Mayo Clinic.

For those who have been prescribed a nuclear test. Ask your cardilogist to describe the test. What drugs are used, what they will do to heart, what you will feel. how long will test last, what will you feel afterwark, what are side affects, what are risks of the test.

Being totally informed will help you not experience those of us that had the test not knowing what was coming and being terrified during the test.
