Nah, it would only go through the finger, maybe a little bit surrounding the hand, but the path of least resistance would not go anywhere near the heart.
Depends the amperage of the socket. If it's high enough, it would start traveling around the body too (probably not high enough to be deadly). If too low, it would still give a nice burned mark around the finger.
By amperage of the socket, I assume you're referring to the breaker that protects it. That usually wouldn't even come into play as the resistance of your skin will draw a low enough amperage that you'd get a shock without tripping the breaker. I've been shocked by 120 plenty of times. Older electricians used to wet their index and middle fingers and touch them across the leads to see if they were alive before working on them (that was b4 capacitive pen testers).
Years ago working on a mechanical lighting circuit timer, I bumped a finger against a 277v line while the heel of my palm was against the grounded enclosure. Literally felt like a hammer blow for several long minutes, but there was no burn. Kids these days have more Hollywood imagination than they do street smarts or experience.

Yes, that's what I meant. We're on 240 here, and accidentally touching a live cable gives you a very nice unexpected adrenalin kick.
