Why do you colapse immediatly after your heart has stopped beating because of a heart attack and not a few minutes later after your body has run out of oxygen?

I feel like it’s the same reason that some people faint when they get their blood drawn vs. don’t faint when they hold their breath. I think our brains need a lot of blood and so losing a significant amount (which happens quickly if your heart isn’t beating) causes you to lose consciousness (maybe as a way to preserve energy?)
