Final answer:
A damaged right bundle branch will prevent the transmission of the action potential to the Purkinje fibers in the right ventricle, obstructing the normal electrical stimulation required for ventricular contraction.
Step-by-step explanation:
A damaged right bundle branch will prevent the passage of the action potential to the Purkinje fibers in the right ventricle. The right bundle branch is integral to the cardiac conduction system, which carries the action potential initiated by the sinoatrial (SA) node through the atrioventricular (AV) node, then to the atrioventricular bundle (Bundle of His), before reaching the bundle branches that divide to supply both the left and the right ventricles. The right bundle branch specifically supplies the right ventricle and facilitates the spread of the action potential to the right ventricular myocardium, including the Purkinje fibers, which are essential for triggering ventricular contraction.
