Abstract

On 149 preparations of the heart of human fetuses 16-32 weeks of evelopment, the patterns of the structural organization of the conducting system in relation to the structure of the organ were studied using generally accepted morphological methods. In fetuses of the same age, 3 types of structural organization of the conducting system were revealed. Each type corresponds to a set of specific characteristics of the atrioventricular node, the bundle of the same name, and its legs. Types of structural organization of the conducting system areformed in the prenatal period
