, The impulse causes the atria to contract.
The impulse travels from the AV node through the bundle of His.
List in order the pathway of the normal cardiac
impulse starting at the SA node.
The impulse divides into the left and right bundle branches.

is linked to stimulation of which component?
The sympathetic nervous system is responsible for increasing the rate of cardiac impulse initiation
A. Purkinje system at the SA node. It also assists with node impulse conduction and cardiac contractility.
