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 10min 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 10min 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."
