Re: Passing out from adrenaline?



Hi Jack, Adrenaline DOES have something to do with all this, the way my cardiologist explains it. Adrenaline speeds up, and the Vegas Nerve slows down. In people with VVS, this slowing down is overexagerated, which causes the drop in blood pressure.

Also....I'm an athlete too (swimmer, but former cc runner!) and i can always kind of tell when i have some extra adrenaline becuase im used to that feeling from races and sure you can tell too. But ive noticed even a small spike in adrenaline, from somethingas simple as speaking in front of a group in class (and i by no means have a phobia of public speaking) can bring on some VVS-ish symptomes.
