The conduction system of heart depends on the below main components. They are
The SA node which is also known as the anatomical pacemaker,
The AV node,
Bundle of HIS,
Purkinje Fibers and
Bundle branches.
It all starts with a contract of atrial muscles that was induced by the SA node. The initiation of contraction travels from the SA node to the AV node and other above said components and make the ventricles to contract.
