Arrhythmias and Conduction Disturbances in Children at the Department of Child Health, School of Medicine University of North Sumatra/Dr. Pirngadi Hospital Medan
A retrospective study on arrhythmias and conduction disturbances was conducted in 1986 in the Division of Pediatric Cardiology of Dr. Pirngadi Hospital, Medon. There were 106 (35.33%) cases with arrhythmias and conduction disturbances out of 300 patients studied. The most common type of arrhytmia among the patients under 5 was intraventricular conduction defects, whilst in the age group of 5-10 were sinus tachycardia and intraventricular conduction defects, and in the age group of 10-15 was first degree A-V block.Rheumatic heart diseases and VSD were the most common cardiac diseases associated with arrhythmias, where the frequency were 18.86% and 10.37%, respectively. Arrhythmias associated with several extracardiac diseases were found in 60 (56.61%). Two out of 7 cases who was rreated with antia"hythmic agents died with SVT associated with bronchopneumonia, and atria/fibrillation associated with gastroenteritis, dehydration and malnutrition. Treatment against the main diseases (without antiarrhythmic agents) was done in the remainders. Even though the overall mortality rate was 13.20%, it was not due to arrhythmia itself but most of them died of non-arrhythmic origin.
