What is the use of Bundle of His in the conduction of cardiac impulse?
The heart beat originates from SAN (sino-atrial node )and passes to AVN (auriculo-ventricular node). The impulse is then picked up by the bundle of His, which lpasses to the network of Purkinje fibres.
The bundle of His is essential for the conduction of cardiac impulse because it forms the continuity between arterial and ventricular muscles. It transmits impulses from the atrioventricular node, located at the inferior end of the interatrial septum, to the ventricles of the heart
