Background. Premature ventricular contractions are early depolarizations of the myocardium originating in the ventricle. PVCs are common with an estimated prevalence of 40% to 75% in the general population on 24 to 48 h Holter monitoring. Frequent premature contractions are rare in healthy children and young ad Objective of the study. Evaluation of the spectral parameters of heart rate variability at children with supraventricular and ventricular premature beats. Material and Method. The study included I group 160 (84,2 %) children with premature supraventricular and ventricular beats, average age (13,32±0,23) years and II group, healthy children 30 (15,79 %), average age (12,2±0,72) years, who were examined with ECG, ECOCG, ECG Holter monitoring over 24 hours, and ambulatory monitoring of blood pressure over 24 hours. Results. Ambulatory ECG Holter monitoring for 24 hours have been determined supraventricular premature beats in 86,25% cases vs 13,33% healthy children (p<0,001), ventricular premature beats in 18,75% cases I group vs 3,33% II group (p<0,05), sinus tachycardia in 75,50% children vs 43,33% healthy children (p<0,001) and supraventricular tachycardia in 43,38% cases I group vs 13,33% II group (p<0,001). Spectral parameters of the heart rate variability at children have been calculated during 24 hours period and there were observed a prevalence of waves with low and very low frequency at children with premature beats. Conclusion. Results of the study showed that cases from I group are associated with supraventricular premature beats in 86,25% cases. Analysis of the spectral parameters of the heart rate variability on ECG Holter monitoring over 24 hours, demonstrates prevalence of waves with low and very low frequency at children. |
