A group of modified muscle fibres, Purkinje fibres, forming a part of the impulse-conducting system of the heart. It arises in the atrioventricular node and continues in the interventricular septum as a single bundle, the crus commune. It divides into two trunks that pass respectively to the right and left ventricles, fine branches passing to all parts of the ventricles. It conducts impulses from the atria to the ventricles, and this initiates ventricular contractions. It was noted in 1892 by Stanley Kent, but was more fully described in 1893 by Wilhelm His.
