Abstract

Objective:
Ostium secundum defect is the common cause of RA enlargement. The aim in this study is to evaluate P wave dispersion in children to the size of atrial septal defect.

Method:
Forty–one children with isolated secundum atrial septal defect (and 41 age-matched controls evaluated. Using the same 12 lead ECG device in resting position, P maximum and P dispersion measured.

Results:
Mean P dispersion in atrial septal defect children is prolonged compare to the controls (P dispersion: 29.1±10.1 vs. 25.3±5.5 ms, P=0.009). And children with right atrial dilation had significantly longer P maximum (101.2±14.1 vs. 81.7±12.3 ms, P<0.001) and larger P dispersion (35.0±11.4 vs. 26.5±8.3 ms, P=0.003) compared to those without right atrial dilation.

Conclusion:
Children with moderate to large sized ASD are valuable to have prolonged. Atrial conduction time in the form of P duration and P dispersion. Also, it’s a good tool for diagnosing ASD in places where echocardiography imaging is not available. We can also differentiate between small ASD and large one based on P dispersion.
