Background: Atrioventricular septal defect (AVSD) is a congenital heart disease resulting from abnormal development of the endocardial cushions, leading to defects of the atrial and ventricular septa and atrioventricular valves. AVSD is frequently associated with Down syndrome and may cause significant hemodynamic disturbances if not detected early. Electrocardiography (ECG) is a simple, non-invasive diagnostic tool that provides important information regarding cardiac electrical activity and structural abnormalities in children with AVSD.
Methods: This cross-sectional analytic observational study included 35 children aged 2 months-18 years with echocardiography-confirmed AVSD at RSUP Dr. Sardjito (2021-2025), excluding those with prior heart surgery. Data from medical records underwent descriptive analysis (median/IQR for continuous variables, frequency for categorical) using Kruskal-Wallis and Fisher exact tests. ECG parameters covered axis, rhythm, hypertrophy, PR interval, QRS, and more.?
Results: Dominant findings Right Axis Deviation (RAD) 45.7%, Right Ventricular Hypertrophy (RVH) 60%, sinus rhythm 88.6%, Left Axis Deviation (LAD) 28.6%. Median heart rate 150 bpm, PR interval 121 ms, QRS duration 80 ms. No significant differences across AVSD types (complete 17.1%, partial 20%, intermediate 62.9%; p>0.05 for all parameters), though complete AVSD descriptively showed predominant RAD.?
Conclusion: Typical ECG features in children with AVSD include RAD and RVH, unaffected significantly by AVSD type. Findings aid early diagnosis and monitoring, with recommendations for larger longitudinal studies.
