The cardiac conduction system in children: its structural characteristics and its role in arrhythmogenesis
Developmental abnormalities and disruption of the anatomical integrity and physiology of the cardiac conduction system can give rise to different types of arrhythmias. The anatomic features of the main structures of the cardiac conduction system in children are considered. The paper gives data on the accessory conduction pathways involved in the Wolff—Parkinson—White syndrome. It considers some causes of the formation of higher arrhythmogenic sites during cardiogenesis and postnatal development of the cardiac conduction system in children. Data are given on a possible association of the clinical manifestations of a number of tachycardias with the pattern of cardiac conduction system development in children.
