Do people die faster when stabbed in the heart or stomach?

I don't think that's the sort of question to answer without doing a little more research. Here's what I've found:  
Dying from a stab wound depends on a lot of factors. If the wound bleeds heavily, then the victim may bleed to death. It's also important where on the body the stab wound is - for example, a wound to the neck or the heart is particularly likely to be fatal, whereas a wound to the hand or arm isn't. But the exact effects of a specific location are hard to say from the information I have, so it's best to say that both stabbing a victim in the heart or stabbing them in the stomach are reasonably likely to be fatal.
