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?

Question

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?

Answer 1

The brain *very quickly* notices that the oxygen level sinks, and breathing goes through the ceiling. Without much success, though. You’ll get an adrenaline boost. But you stay conscious for a short while. But that’s not fun, as there is only one thing on your mind: *PANIC*. I can tell you, it’s not funny. 0/10, can’t recommend.

I was lucky, my heart restarted from one of the fail-safe circuits the body has, or else I would not type this.
