Abstract:
The change in the "refractory window" was assessed as a possible indicator of successful slow pathway modification in 26 pediatric patients with persistent dual-atrioventricular node physiology. The "refractory window" was defined as the difference between the fast and slow pathway effective refractory periods. A significant decrease in the refractory window (p <0.001) after successful slow pathway modification was found.
