Influences on fast and slow pathway conduction in children: does the definition of dual atrioventricular node physiology need to be changed?

Abstract

The present study clearly establishes that there are a variety of influences on fast and slow pathway conduction properties and that there are subpopulations of children in whom these conduction properties differ. A more detailed comparison of data from these subpopulations may provide more information regarding the relative strength of these influences and how they change. In turn, this may lead to a more accurate and useful definition of dual AV node physiology in children and an improved understanding of the etiology of AVNRT.
