Do you go unconscious and die instantly the second your heart stops? If so, what causes that to happen instead of taking a little while for your brain to actually “turn off” from the lack of oxygen?

Like if you get shot in the head, your death is obviously instantaneous (in most cases) because your brain is literally gone. Does that mean that after getting shot directly in your heart, you would still be conscious for a little while until your brain stops due to the inability to get fresh blood/oxygen to it?

No, you don’t. You stay conscious for a few tens of seconds.

Apparently, back when smoking was common and good safety procedures were not yet universal, you’d occasionally find an electrical maintenance person dead next to a fuse box, holding a cigarette. The maintenance person had touched a live wire inside the box with their right hand while holding the grounded metal of the box open with their left hand and thought they’d received a non-fatal shock, when the shock had in fact silently stopped their heart. Then they’d start feeling tired from insufficient blood flow, and get out a cigarette because nicotine is a stimulant. Then they’d fall unconscious and eventually die.
