WebThe heart's control system. A heartbeat is caused by an electrical impulse traveling through the heart. The heart's built-in electrical system controls the speed of its pumping. The electrical impulse originates in the sinus … Electrical signals arising in the SA node (located in the right atrium) stimulate the atria to contract. Then the signals travel to the atrioventricular node (AV node), which is located in the interatrial septum. After a short delay that gives the ventricles time to fill with blood, the electrical signal diverges and is conducted through the left and right bundle branches of His to the respective Purkinje fibers for each side of the heart, as well as to the endocardium at the apex of the heart, t…
