cardiac conduction system

Function

• under normal conditions, the pacemaker function of the heart resides in the sinus node, the impulse is propagated through the atria to the AV node, & after a delay in the AV node through the bundle of His with subsequent branching into right bundle branch & left bundle branch conducting to the ventricles.
