Maybe our medical professionals here can answer this better, but it was my understanding that unless the brain or spine are hit the body will still mostly function, even with a direct hit to the heart, the fatally wounded person could continue to pull the trigger for 10-15 seconds until lack of blood to the brain caused the person to lose consciousness.
Yes, it's physically possible for certain people to do that, but whether they actually will is another story. In rare cases sheer adrenaline has kept mortally wounded people fighting for quite some time, but those cases are quite rare - people are not deer.
In any case, if someone is still pulling the trigger after being mortally hit, the person confronting them is going to keep shooting them until they stop, as they are obviously still a threat. More importantly, if they're dying because they've been shot in the heart, that trigger is going to get very hard to pull very fast. Even if adrenaline keeps them shooting, they aren't going to reload, and that 10-15 seconds will be mostly moot. They won't be able to reload and will run out of ammunition well before 10 seconds is up, or they'll get shot a bunch more times and be unconcious or die sooner.
That brings us to another point. Many people won't keep shooting even when they might be physically capable of doing so. How the person mentally reacts to being shot is a very unpredictable thing. Not only that, but even if a shot is not instantly fatal, lots of hits can cause unconciousness, and even just the mental shock of being shot can do it.
Regardless, the chance of a mortally wounded people spraying bullets all over the place is below miniscule.
