Q

electrical conduction system within heart

A

SA node is primary pacemaker and initiates atrial contraction, travels to AV node which is backup pacemaker and acts to depolarize atria and slow impulse, then atrial contraction begins and conduction travels to heart apex, then travels to bundle of his and bundle branches, then travels to purkinje fibers and through ventricular myocardium, causing ventricular contraction
