Bundle of His - Animated Concise Dictionary of Cardiology

Bundle of His or Atrioventricular (AV) bundle is a band of specialised muscle fibres that connect the atria with the ventricles and maintain the normal sequence of heartbeat. They originate from the AV node in the interatrial system, pass through the atrioventricular junction, and then divide into right and left bundle branches. Within the ventricular myocardium the branches break up into fine fibres, called Purkinje fibres. The AV bundle, bundle branches and Purkinje fibres convey electrical impulses from the AV node to the apex of the myocardium setting off impulses for ventricular contraction and pumping blood into the pulmonary artery and the aorta.
