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?
In: Biology
Depending on the efficiency of your heart (ejection fraction and a few other parameters), if your heart stopped, your pressure would tank and you would lose consciousness pretty quickly, although, you would not be dead or even brain dead for a few minutes. The pressure created by your heart adds to the ability of your body to exchange oxygenated blood with deoxygenated blood!
