From watching alot of movies and series in my lifetime, one thing has always struck me as rather illogical.
When people are either shot or stabbed in the heart they die very fast.
Is this just fiction or reality, and why is it so?
As I see it blood will still pump even if a hole in the heart causes you to bleed internally. The lungs and brain will still get blood just with a lower rate due to a lower pressure(?), and not only should you remain alive but also conscious for some time.
Are movies just making this happen as a dramatic effect or something, or is there a reason you die so fast from - for example - a stab to the heart by a knife or gunshot wound.
