Ok. The heart doesn't just beat magically (but that would be cool), it uses a complex system of nodes and fibers to keep the beat going. Let's get started
All heart pulses start near the right atrium of the heart. Then the move diagonally to the left ventricle. They begin at the sinoatrial node (SA node). Then they move to the atrioventricular node (AV node) which causes the pulse to slow down. Then the AV node sends it down through the bundle of His which is located in the interventricular septum. The signal divides into the left and right bundle branches which spread to the left and right ventricles. The branches then lead to the Purkinje fibers which is wear the signal stops.
THIS IS VERY CONFUSING!!!!
IT WILL BECOME EASIER WHEN WE TALK ABOUT THE EKG
I hope this helped!
