The effects of surgical repair on P-wave dispersion in children with secundum atrial septal defect

Introduction Atrial septal defect (ASD) is one of the most common congenital heart diseases in children. P-wave dispersion has been reported to be associated with non-homogeneous propagation of sinus impulses. The heterogeneity of atrial conduction time may predispose the atria to arrhythmias. The a...

Description
Summary:Introduction Atrial septal defect (ASD) is one of the most common congenital heart diseases in children. P-wave dispersion has been reported to be associated with non-homogeneous propagation of sinus impulses. The heterogeneity of atrial conduction time may predispose the atria to arrhythmias. The aim of this study was to determine the impact of surgical repair on P-wave indices in children with isolated secundum ASD. Methods Children with isolated secundum ASD undergoing surgical repair ( n =50; mean age, 7.0±3.0 years) and healthy controls ( n =51; mean age, 7.6±2.7 years) were compared. Maximum P-wave duration (Pmax), shortest duration (Pmin) and P-wave dispersion (Pd) were measured using 12-lead surface electrocardiography. Results Mean Pmax was found to be significantly higher in children with ASD compared with controls (95.2±10.8 vs 84.1±9.2 msec; P
