I forgot the picture of the standard cyl head. Here it is.
An electroechocardiogram is needed once in a lifetime for FIM. I had one a few years back and passed. The stress test needs to be done every three years and this was the year to redo it. The nurse took my baseline electrocardiogram last week and she told me to show up this afternoon for the test. She said "Don't eat a big lunch. We don't want you puking on our machine." Lovely advice. I had strawberry pie for lunch. At least it would taste good coming back out.
The nurses wired me up. I said "I am a pre-old guy. Sort of delicate. Stop the machine when I have passed the test. Do not try to kill me like you did last time." The nurse said "You stop the test, not us. Tell us when you cannot handle any more." Wonderful. Last time that meant I wanted to barf, saw black spots in front of my eyes, and had horrible leg cramps.
The machine started. The belt was level and it moved slow. Gradually they increased the speed and the tilt. I walked faster and faster. The table was tilted steep and the speed was turned up more. I needed to run. I did this for a half second and said "enough." They stopped the awful device.
The nurse said "Had enough?" I said, "I'm not really tired. It is undignified for a gent my age to engage in running." She looked at the graphs, etc and said, "Well, you passed. Another 20 seconds and we would have rated you excellent." That would have been a long 20 seconds, for sure.
