[Types of anatomic correspondence between the conducting system and the heart]

The principles of a quantitative determination of characteristics concerning the types of anatomical correspondence between the conduction system and the heart at its congenital malformations are presented. This makes it possible to establish that the topographoanatomical type of the conduction system depends on the peculiarities of the heart structure at its congenital malformations rather than from changes in the structure and position of the parts of the conduction system, or the conduction system as a whole according to the types of congenital heart malformations. The mechanism of the left-sided position of the atrioventricular bundle (His bundle) in some congenital malformations of the heart is explained.
