Status of cardiac conduction and heart rhythm of children with congenital minor abnormalities of heart development

Abstract

In order to study the status of cardiac conduction and heart rhythm of children with minor abnormalities of heart development were examined 378 schoolchildren in 6-17 ages. Children, depending on the type of minor abnormalities of heart development were divided into three groups: children with minor anomalies of the mitral subvalvular structures -108, minor anomalies of the tricuspid valve -92 and abnormal chords of the left ventricle -82. The rest of the 96 children was in the control group. The frequency of sinus arrhythmia, bradycardia, supraventricular and ventricular arrhythmias was significantly higher from the control, in all clinical groups with a slight predominance in group of children with abnormal chords of the left ventricle And the signs of early repolaization of ventricular myocardium and incomplete right bundle branch block were significantly higher in group of children with abnormal chords of the left ventricle.
