Abstract

Introduction: The atrial septal defect (ASD) is an acyanotic congenital heart defect
with left to right shunting, that can occur in any portion of the atrial septum.
Auscultation and electrocardiographic (ECG) findings are characteristic for diagnosis
of atrial septal defect. This study was done for detection of sensitivity and specificity
of these findings in diagnosis of ASD in children.
Methods: This descriptive-analytic study was done on 100 patients with ASD that
referred to pediatric heart clinic during 2000-2004 and compared with 205 normal
children that were matched for age and sex. Physical examination, ECG and
echocardiography of two groups were compared. Data were collected and analyzed
with SPSS software and statistical tests.
Results: Mean age of patients with ASD was 7.71±4.60 and in control group was
6.92±4.75. Male to female ratio in case and control groups were 1.56/1 and
1.07/1, respectively. Sensitivity and specificity of fixed and wide splitting of the
S2 in patients with ASD were 96% and 100%, respectivity. Sensitivity and
specificity of ejection systolic murmur in pulmonic area in patient with ASD were
97% and 100%, respectively. Sensitivity and specificity of rsR' pattern in ECG
of patients with ASD were 79% and 99.02%, respectively. Sensitivity and
specificity of right ventricular hypertrophy (RVH) without rsR' in ECG of ASD
patients were 29% and 100%, respectively. Sensitivity and specificity of tall p
wave in the patients with ASD were 39% and 100%, respectively. Based on
statistical analysis, fixed and wide splitting of the S2 and ejection systolic
murmur in pulmonic area are more helpful for diagnosis of patients with ASD
than other findings.
Conclusion: The findings of this study showed that auscultatory and ECG findings
of ASD are as helpful in children as in adults. This is especially true in centers that
modern diagnostic instruments (such as TEE and TTE) are not available.
