The electric current that drives comes in an area of the heart – the sinus node, at the right atrium – which plays the role of power. It then goes through the two atria (right and left) and causes contraction, which causes the blood from the atria to the ventricles. He then came into the area at the junction between the atria and ventricles, the atrio-ventricular node, where it is dispatched to the two ventricles, causing a contraction is homogeneous and powerful than the blood so the heart and circulates throughout the body.
