Key result
Atrioventricular node reentry tachycardia was diagnosed in 6 of 52 infants (11.5%) undergoing transesophageal study for paroxysmal tachycardia, indicating the substrate is present early in life.

Supports AVNRT as cause of neonatal tachycardia; extends timing evidence but hypothesis-generating for infant management.
Observational (n=52)
The anatomical substrate for AV node reentry tachycardia is present early in life and can cause clinical arrhythmias even in the newborn period.
Crosson et al. (1995) conducted an observational in Paroxysmal tachycardia (n=52). Transesophageal electrophysiological study was evaluated on Frequency of atrioventricular (AV) node reentry tachycardia. Atrioventricular node reentry tachycardia was diagnosed in 6 of 52 infants (11.5%) undergoing transesophageal study for paroxysmal tachycardia, indicating the substrate is present early in life.
