Association between nonreentrant supraventricular tachycardia and atrioventricular node reentrant tachycardia: a presentation of dual AV node physiology.
Persistent simultaneous conduction of P waves over a fast and a slow nodal pathway defines the nonreentrant type of supraventricular tachycardia, usually not associated with reciprocating movements. We report a unique association between this uncommon tachycardia and a usual AV nodal reentrant tachycardia, made possible by the existence of three different nodal pathways.
