Characterizing Dual Atrioventricular Nodal Physiology in Pediatric Patients with Atrioventricular Nodal Reentrant Tachycardia

Abstract

Neither the common definition of dual AV nodes or redefining an AH jump as some value <50 msec are reliable methods to define dual AV nodes or to predict AVNRT in pediatric patients. PR > or = RR is a relatively good predictor of AVNRT.
