I did the nuclear/treadmill test before I had my cardioversion last year. My heartrate was already high before the test because I had to be off my meds for 24 hours prior. So after straining to make it 5 minutes on the treadmill, my heartrate hit 205 bpm. It felt like my heart was going to explode out of my chest. No, it wasn't a fun experience, yes, it took awhile, although not as long as it would have taken had my heartrate been normal to begin with, but like Sal mentioned, it's better than having a heart attack. And if I
am going to have a heart attack, what better place to have it than in the hospital on a treadmill?
