Nuclear Stress Test

Yes, but it's been a few years...but I don't recall it going that long ..for me.

Admittedly, I was being tested for some cardiac arrhythmia issues. I recall it was called the Mibi stress test...and it was maybe 20-30 minutes long..but if you add in the time to prepare and take the drug and then afterward make sure it's out of the system ..perhaps it was longer an hour tops.

Maybe yours is a different nuclear stress test,....testing a different area.

I had a bunch but never completed them. My mes kept my heart from pumping fast so I would tire out halfway into the test.
In my life Ive learnt to walk not run an to not sing while hiking. It takes me a while to make distance.
But my nuclear tests showed my heart was not clogged up.

it appears to be two stages: injection / waiting / activity then injection / waiting / inactivity
