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.
What else can I help you with?
Correct order of intrinsic cardiac conduction?
Its one of these, cant remember which one though: AV node, SA node AV bundle, Purkinje fibres. SA node, AV bundle, Purkinje fibres, AV node. SA node, AV node, AV bundle, Purkinje fibres. Purkinje fibres, SA node, AV node, AV bundle.
What is the correct sequence of parts that function to carry cardiac impulses?
SA node, AV node, AV Bundle, Purkinje Fibers
The correct sequence in the conduction system of the heart is?
SA node, Internodal pathways, AV node, Bundle of His, Bundle branches, Purkinje fibers.
What are the Fibers of ventricular bundle?
The fibers of the ventricular bundle, also known as the bundle of His, are specialized cardiac muscle fibers that conduct electrical impulses from the atrioventricular (AV) node to the Purkinje fibers in the ventricles. These fibers play a critical role in coordinating the contraction of the ventricles during the cardiac cycle, ensuring effective pumping of blood out of the heart.
What is the correct sequence of cardiac electrical activity?
The impulses from SA node spread through out the atrial musculature in about 0.09 seconds, and parallel to it, the impulses also reach the AV node. From AV node, after a delay of about 0.12 seconds they pass to the inter ventricular septum through the Bundle of His, which soon divides into Left and Right Bundle branch and ultimately into the Purkinje fibers which first depolarize the endocardium of the ventricles and then the rest of ventricular musculature. SA Node --> Atria, AV node --> Bundle of His --> Right & Left Bundle Branches --> Purkinje fibers
What is the correct path for the transmission of an impulse in the instrinsic condition system of the heart?
sinoatrial (SA) node, atrioventricular (AV) node, atrioventricular (AV) bundle, right and left bundle branches, Perkinje fibers
What depolarise immediately after the AV node depolarises?
You have the specialized conduction tissue called as bundle of His. This bundle spread across the inter ventricular septum to cover the walls of both the ventricles. The bundle was named after the name of God, so the name goes as bundle of His. These cells get depolarized immediately after the the AV node.
Network of conducting tissue located in the ventricular myocardium?
The cardiac conduction tissues in the human heart comprise specialized myocytes that can be differentiated from working myocardium with routine histological staining. They are located in specific regions of the heart to form the sinus node and the atrioventricular (AV) node, which then extend into the AV bundle and bundle branches
What are the pathways through the body for electrical impulses?

What are the structures involved in the conduction system of the heart?
Internal pacemaker , sinoatrial(sa) node, atrioventricular (av) node , atrioventricular bundle (bundle of his ) and purkinje fibres.
What conducts impulses from the AV node to branches which lead to the Purkinje fibers?
Av bundle
The normal pattern of impulse conduction through the heart is?
SA node, AV node, AV Bundle, Bundle branches, subedocardial branches (purkinje fibers)
