Electrical Flow Of The Heart In Order. the electrical system of the heart is critical to how it functions. The heart's pumping action is controlled by an. the electrical stimulus travels down through the conduction pathways and causes the heart's ventricles to contract and pump out blood. the ventricles pump the blood to the lungs and throughout the body. the pacemaker cells create electrical signals by the movement of electrolytes (sodium, potassium, and calcium ions). The electrical impulse starts on the right side of the upper chamber in an area called the sinus node. The electrical activity spreads through the walls of the. the electrical impulse begins at the sa node, located in the right atrium. It controls the electrical impulses that. The 2 upper chambers of the heart (atria) are stimulated first and contract for a short period of time before the 2 lower chambers of the heart (ventricles). In order for the heart to squeeze and pump blood, it needs a sort of spark plug, an electrical impulse, to start a heartbeat. the heart's electrical system in the simplest of terms, the heart is a pump made up of muscle tissue.
