i had this problem for a few years.
but it's not something that happens every single day.
it happens once in a while.

so what happens is that my heart would start pumping like crazy.
and then my chest would really hurt.
my heart would start pumping really big.
it would pump up to the point it hurts and i have to stop everything i'm doing and then it would return back to normal.
it would also make me dizzy and faint.

anyone know whats wrong with me? o.o

You should go to a cardiologist and get an EKG.
I had a condition called SVT (Supraventricular tachycardia), and it was when my heart would be reallyyyyyy fast. Up to about 130 i'll say.
I never had chest pains, but my heart would beat at crazy speeds.
And I also felt very cold and sweaty.

my heart doesn't necessarily beat fast
it just beats harder?
does that make sense? o.o

I think it's best if you go see a heart doctor.
They're more likely to give you the correct answer than here.

But from reading about your symptoms it sounds like one of my friends symptoms.
She has heart problems, she inherited it. She has to stop walking at one or two points on a hill on the way back to her house because of it.
Maybe you should consult your mum or dad about it?
