For Diagnosis and Investigation "I took the Lexiscan stress test yesterday. The hardest part of the test was lying still for 45 min. The chemical was injected during the last 10 min, and I felt no real side effects. I had a slight taste in my mouth for maybe 20 seconds, and I noticed that my heart rate increased. After a couple of minutes, my heart started slowing, and after the 10 min period, I felt normal. If you are scheduled for the test, stop worrying, it's not that bad. Don't stress out from all the horror stories you read on the Internet."

For Diagnosis and Investigation "Wasn't fully prepared for the immediacy of the effect of this drug. As soon as it was injected, I felt like I was suffocating, almost claustrophobic. It plateaued quickly and came down, went away quickly, but it was scary initially. Feel the cardiologist could have done a better job of prepping me for the effect. It certainly raised my heart rate, I'll give it that."

For Diagnosis and Investigation "F, 115 LB, 55. I had it done in a hospital setting while under observation. It does make your heart race, but it is very quick. They gave me coffee afterward. The staff were excellent to keep me calm. Knowing nothing beforehand is the best. Just surrender to whatever happens. Result: I had no blockages."
