Hi Evergreen, Yes, I have had the Thallium Stress test done a couple of times. My background is I am 34yrs old Female, I have MS and an autonomic disorder known as Multiple System Atrophy which has made the electronic parts of my heart fail. Basically it is stable but my brain sends it the wrong infomation, if that makes any sense? I had a pacemaker implant 3 yrs ago for extremely low heart rates now they are just all over the place as is my blood pressure.
Back to the TST, it was not painful in the least bit. Basically I just laid on the table while this big x-ray thing moved above me taking pictures. I did have to have an IV inorder to chemically induce different HR's. But it didnt make me sick and I didnt have to do the treadmill or bike along with this test either.
I hope you post again and let us know how it went.
