INSTRUMENTAL CHARACTERISTICS OF HEART RHYTHM AND CONDUCTION DISORDERS IN CHILDREN WITH MINOR HEART ANOMALIES, COMPLICATION PREDICTION CAPABILITY

The objective of our research was to establish specific features of cardiac rhythm and conduction disorders in children with minor heart anomalies (MHA) on electrocardiography and Holter monitoring, and to elaborate a predictive model of sudden death syndrome (SDS) in children. Material and methods. 168 children aged 2-17 years were examined. The incidence of sudden death syndrome in children was studied in Grodno from 2008 to 2017. Results. It was found that cardiac rhythm and conduction disorders in children with MHA were detected more often on Holter monitoring (HM) than on ECG compared to children without minor heart anomalies. A predictive model of SDS in children with left ventricular false tendons (LVFT) was elaborated (sensitivity 100%, specificity 100%). Conclusions. HM is necessary for children with MHA to monitor the presence of arrhythmias. The use of the discriminant equation will enable to perform targeted selection of children with LVFT to the high-risk group of the SDS.
