What are cardiac AV bundle?

The cardiac AV bundle, also known as the Bundle of His, is a specialized bundle of heart muscle fibers that conducts electrical impulses from the atrioventricular (AV) node to the ventricles. It plays a crucial role in coordinating the heart's contractions, ensuring that the atria contract before the ventricles. The bundle splits into right and left bundle branches, which further distribute the impulses throughout the ventricles via Purkinje fibers. Proper functioning of the AV bundle is essential for maintaining an effective heartbeat and overall cardiac rhythm.
