In cardiac conduction, what follows the AV node?

Purkinje fibers
Right and left bundle branches
SA node
Bundle of His

The correct answer is: Bundle of His

After electrical impulses pass through the AV node, they then travel through the Bundle of His. This is followed by the right and left bundle branches and then the Purkinje fibers. The SA node, also known as the sinoatrial node, is responsible for initiating the electrical impulses that travel to the AV node, so it does not follow the AV node. Therefore, options A, B, and C are incorrect.
