T Hara (1967) studied Cardiac conduction system anatomy (n=75). Morphological and histochemical examination was evaluated on Morphological and histochemical characteristics of the cardiac conduction system. Morphological and histochemical examination of 75 dog hearts detailed the structure of the sinus node, atrioventricular node, bundle, and Purkinje fibers, noting abundant glycogen throughout.
