Why the study?
What is the prevalence of dual AVN pathways in children and young adults undergoing electrophysiologic investigation?
What is the prevalence of dual AVN pathways in children and young adults undergoing electrophysiologic investigation?
Dual AVN pathways are a common electrophysiologic finding in children, particularly those with PSVT, and are equally prevalent regardless of congenital heart defect correction status.
No takes yet. Share an insight, caveat, or question.
May guide EP evaluation in pediatric PSVT; leaves open whether correction status modifies arrhythmia risk in congenital heart disease.
Thapar et al. (1979) studied this question.
