You are probably correct. This was more than 20 years ago and we all know how tricky memory can be.

If the under-perfused tissue/cells are in your brain, you become can become distressed, confused, "light headed" or experience loss of consciousness..

I was light headed the first go around. The second, and recorded blackout, was just instant black.

No one mentioned seizure to me.

Always interested in learning so, no, not more than I want to know. I am guessing you are an M.D. Regardless, thanks for the input.
I'll try to find the printout and scan the relevant part of it. If I succeed, I'll post it. My, perhaps shaky, memory is the line was somewhat erratic, then very fast and erratic, then flat line.
And, yes, I feel very lucky to be alive.
