When I awoke from a cardiac arrest, I was surrounded by 15 medical pros, one of whom was pounding on my chest. I later found out that I actually arrested twice and they used paddles on me 7 times. Don't remember any of that.
Gotta say CPR hurts like hell. My chest was sore for days. Couldn't breathe without pain.
Thank God for CPR. Brought me back from the dead.
