title: Electrocardiographic demonstration of dual atrioventricular nodal pathways in children.
abstract: Dual atrioventricular nodal pathways, as evaluated by electrocardiography, were found in two children without arrhythmias over a six year period. Although none have developed tachycardia, they have the substrate to develop atrioventricular reentrant tachycardia.
