Abstract
Goal. To study the long-term effect of the SARS-CoV-2 virus on the cardiovascular system in children of the Smolensk region.
Materials and methods. Holter ECG monitoring for children aged 1 month to 18 years who suffered from mild or moderate COVID-19 within 3 to 12 months after discharge.
Results. Sinus tachycardia unrelated to physical activity was recorded in 35%, sinus bradycardia - 25,9%. Non-sinus rhythm was observed in 19 children. 125 children had atrial extrasystoles. Ventricular extrasystoles were registered in 35% (single – 18,7%, by type of bigeminia – 17,9%, trigeminia – 9,4% and quadrigeminia – 1,8%). Among the cardiac conduction disorders, the leading position was occupied by atrioventricular blockages of 1–3 degrees, conduction disorders along the right and left legs of the Gis bundle, as well as their complete and incomplete blockages. Rhythm pauses were observed in 4,1% of cases, very low HRV was observed in 9,7% and QTc prolongation was observed in 40.2% of children, respectively.
Conclusion. Cardiovascular lesions are one of the most central problems of post-covid. Various cardiac arrhythmias and conduction disorders have been recorded, and their frequency has been shown in pediatric patients aged 1 month to 18 months.
