Actually, you are not entirely correct about what makes the heart beat.  Although it is true that certain chemicals make cause contractions and expansions, what makes the heart beat is an "electrical" impulse that "sets off" the chemicals that permit contraction and expansion of the muscles.  This is why getting certain types of electric shocks can stop your heart, and why a defibrillator works (by literally "jump-starting" the "battery").  As an aside, it is also why certain types of martial arts blows can kill; those blows are targeted at the heart, and the result of the blow is to stop the electrical impulse that keeps the heart going.

Peace.

Breathe, breathe in the air.
Don't be afraid to care.
Leave but don't leave me.

Um, actually defibrillators STOP your heart, in order to allow the natural pace maker to take over again.  It's really electrochemical, not completely electrical, the potential differences being created by varying chemical concentrations, 'tis a complex process
