Does the top half of your heart beat differently from the bottom part of your heart?
No you heart beats as one. It has its own electric pulse of some kind, which tells individual tissues and cells when you beat. There are electrical nodes which act as a circuit. In a normal working heart the beat originates in the sinus node in the right ventrical, the current travels across the chambers (filling them) then initiates the second node (cant remember the name) which causes the contraction of the lower chambers (pushing the oxigenated blood out through the aorta and to the body).
