what events occur with electrical impulses from the arterial ventricular node are transmitted to the entire ventricular system The bundle of His and the Purkinje fibers transmit the electrical impulses from the arterioventricular node to the entire ventricular system. resulting in (______) or contraction from the bottom of the heart?
When SA Node triggers Atria goes into Systole !! and when the signal reaches to AV node and from there it goes to Bundle of His making Ventricle to systole or constrict !!
