The Kardiac Concordance
(Thanks to Dr. Francis)
"...the preliminary blood test was negative."
In the blood sample, doctors look for the presence of an enzyme called creatine kinase (cree-a-teen kine-ace). It is an enzyme released into the bloodstream by suffocating cardiac muscle. If it is present, it indicates that you are probably having a heart attack.
"...a drug was injected into my I.V. that caused my body temperature to rise by about 1000 degrees."
The drug was called nitro glycerine...not exactly the same thing as TNT, but it sure felt like it at the time.
"I don't know what the machine is called,..."
I didn't know at the time. I know now that it is called a Fluoroscope.
It is an iodine-based dye that can be seen using the fluoroscope.
For you scientists out there, the isotopes were either thallium or sestamibi. I'm not sure which as I was very uncomfortable at the time the test was performed. Being radioactive is no fun.
