Introduction. The relatively young science of pediatric cardiology has made enormous breakthroughs in recent years: the labor intensity and complexity of modern diagnostic techniques have increased, and interventional methods of treatment are widely used. Modern pediatric cardiology covers a wide range of diseases: from intrauterine pathology, such as congenital heart and vascular defects, fibroelastosis, various arrhythmias, to acquired diseases represented by arterial hyperand hypotension, systemic vasculitis, autonomic dysfunction, juvenile rheumatoid arthritis.Purpose. To demonstrate the important stages of the development of the children’s cardiological service in Grodno region over a sixty-year period, assess its current state and analyze the dynamics of the incidence rate of children’s heart and vascular diseases during 2005–2019 in this region.Material and methods. During the period of 1960–2019 a retrospective research was carried out using the statistics: report of the chief substitute pediatric cardiologist, report of medical treatment for children during 2005–2019, analytical and conjunctral reports, reviews and references of chief doctors and local pediatricians.Results and discussion. The sixty-years of activity of the children’s cardiological service in Grodno region were analyzed. It was found that over the past 15 years there has been an annual increase in the overall incidence of diseases of the circulatory system (classes I00-I99 ICD 10), while the primary incidence decreased from 331.06 to 265.63 per 100,000 of the child population. The overall incidence of congenital heart defects over the past 15 years was characterized by a low decrease from 916.40 to 800.16 cases against the stabilization of the primary incidence rate.Conclusion. The obtained results indicate the well-organized work of the diagnostic, hospital, dispensary and prophylactic stages of medical assistance to children with cardiovascular pathology.

Цель.

Проанализирована деятельность детской кардиологической службы за 2013–2019 гг., оценена общая и первичная заболеваемость аритмиями. Проведен анализ электрокардиографического скрининга, в ходе которого было обследовано 10 353 ребенка без признаков органической патологии сердца в возрасте 0–17 лет.Результаты и обсуждение. Продемонстрирована многоуровневая система оказания медицинской помощи детскому населению с нарушениями сердечного ритма и проводимости в Гродненской области. Установлено, что аритмии встречаются у 27,78% детей г. Гродно, в гендерной структуре преобладают мальчики. Обобщен опыт работы кардиологической службы на профилактическом, диагностическом, диспансерном и госпитальном этапах.Выводы. Установлены потенциальные резервы для дальнейшего развития в современных социально-экономических условиях. Purpose.

The activity of the pediatric cardiology service in 2013–2019 was analyzed, thegeneralandprimaryincidenceofarrhythmiaswasestimated.Theanalysisofelectrocardiographic screening was carried out, during which 10 353 children without the signs of organic heart disease at the age of 0–17 years were examined.Results and discussion. The organizational technology of the multilevel system of medical care for children with cardiac arrhythmias and conduction disorders in the Grodno region is demonstrated. It was revealed that arrhythmias occur in 27.78% of Grodno children; boys dominate in the gender structure. The experience of the cardiological service at the preventive, diagnostic, dispensary and hospital stages is presented.Conclusions.
