INDIVIDUAL VARIABILITY OF THE STRUCTURE OF THE INTERVENTRICULAR SEPTUM OF THE HUMAN HEART

Abstract

An analysis of structural options for interventricular septum and the corresponding parts of the cardiac conducting system was carried out on a 501 preparation of the heart of fetuses, children, and adults of both sexes. In fetuses and in the postnatal period of ontogenesis of the conducting system and the heart were revealed. The variability of the linear dimensions and shape of the sinus part causes in individuals of the same age a different length and angle of the position of the atrioventricular bundle and its bundles. The shape of the sinus part of the interventricular septum, the ratio of its parameters can be taken for a preventive assessment of the length of the atrioventricular bundle during normal heart development without first isolating it.
