title: [Quantitative analysis of tissue and cellular components of the specialized internodal conductive pathways of the heart].
abstract: A light-optic and electron-microscopic study of internodal specialized pathways in the rat interatrial cardiac septum is reported. The topography of conductive pathways is described. Morphometric investigation yielded comparative quantitative characteristics of tissue and cellular composition of the working and conductive septal myocardium. A single type of myocytes was demonstrated in specialized conductive pathways. The findings were compared with those obtained in other species. Principles of identification of specialized conductive pathways are discussed.
