Arrhythmogenic pattern of Congenital Heart Diseases (CHD) in Children

Abstract

The aim of this work is to detect and delineate the arrhythmogenic Pattern of congenital heart diseases regarding its types incidence, and out come. Background CHD represents the most important components of pediatric Cardiovascular disease. The incidence of CHD in live births ranged from (0.5–3%) WHO. The most life threatening complications of CHD were the different types of arrhythmias. Methodology The present study was conducted upon 100 children suffering from CHD. Also selected 50 healthy child as control group age matched were included. They were following the Outpatient Clinic Abou Riesh Hospital, Cairo University from (2008 to 2011). – They aged from (20 days till 6 years). – All patients were subjected to thorough clinical history and examination, X-ray Chest, ECG -12 leads, long strip lead II and Echocardiography. – Some cases were subjected to cardiac, 24-h ECG recording (Holter). Results All the results were statistically analyzed. – Sex distribution among study was 45% females 55% males. – The incidence if arrhythmogenic pattern in the studied group were (57%) suffering from arrhythmias. While (43%) were not affected. – The percentage of the different types of arrhythmias was as follows: among the affected group. – Atrial fibrillation (21.4%), supraventricular tachyarrhythmia (49.7%), Sick sinus syndrome (5.2%), ventricular tachycardia (5.2%), extrasystole (12%), heart block I(3.5%), heart block type II (3.5%). – Congenital cyanotic heart disease has highly significant statistical correlation with the incidence of arrhythmias pattern ( p – While acyanotic CHD has non significant relation ( p > 0.05). Conclusion – The congenital cyanotic heart diseases have the higher incidence of arrhythmias more than the acyanotic group and control. – The early affection of the different types of arrhythmias are most serious and life threatening.
