A damaged right bundle branch will prevent the passage of the action potential to the:
A)atrioventricular (AV)node.
B)atrioventricular (AV)bundle.
C)Purkinje fibers in the right ventricle.
D)sinoatrial (SA)node.

Question

Quizplus · Accepted Answer

The right bundle branch is responsible for carrying the electrical impulses that stimulate the Purkinje fibers in the right ventricle, ultimately causing the right ventricle to contract. Therefore, a damaged right bundle branch would prevent the passage of the action potential to the Purkinje fibers in the right ventricle.
