Relevance. The peculiarities of clinical course of various types of tachycardia in children have been studied insufficiently, whereas as they are very important in prediction of a disease and development of medical tactics. Objective. Study peculiarities and laws of the clinical course of paroxysmal atrioventricular junctional reentrant tachycardia and define age periods that play an important part in development and progression of the disease. Materials and methods. The study included 149 children with typical (slow-fast) paroxysmal atrioventricular junctional reentrant tachycardia – 85 (57.1 %) boys and 64 (42.9 %) girls. All children underwent complex cardiological investigation. Duration of clinical follow-up was 6.2±3.5 year (from half a year to 17 years). Results. Paroxysmal atrioventricular junctional reentrant tachycardia in children usually becomes symptomatic at the age of 7–15 years, develops in boys more often and seldom resolves spontaneously. The age of 12–15 years is one of tachycardia incidence peaks, when the disease often progresses. Syncopal and presyncopal conditions develop in 37 % of children with tachycardia, usually in several years after the disease onset. Conclusion. Taking into account a high probability of disease progression, possible relapses even after long remission periods, and probability of atrial fibrillation overlay, radio-frequency ablation of the slow way is a method of choice in treatment of this type of tachycardia in children especially over 12 years old.
