The bundle of Kent is an accessory electrical conduction pathway between the atria and ventricles. This pathway is distinct from the usual conduction system which includes the AV node and His-Purkinje system. In Wolff-Parkinson-White (WPW) syndrome, the bundle of Kent provides a path for electrical impulses to bypass the AV node, leading to pre-excitation of the ventricles. This can result in tachycardia due to reentrant circuits.
Given this information, the correct statement about the bundle of Kent is: It is muscular or nodal pathway between the atria and ventricle in WPW syndrome.
