Depends on a lot of factors. Amperage, whether the current is flowing thru the chest, etc. I have been zapped numerous times with 100, and 200v, and even took a big hit from 440v three phase. Been zapped enuf that it does not scare me much.. but I do not really relish it either.
On the other hand, I also saw a guy have his pacemaker screwed up and he had a heart attack from clicking one of those trick lighters that shock ya.
Actually, I was joking. The word "electrocution" means death by electric shock. I thought it was funny that someone was reporting his own death to a newspaper.
