 The article presents the results of detecting predictors of cardiovascular system disorders based on heart rate variability and electrocardiography in children with tonsillitis syndrome in acute respiratory diseases of various etiologies. A prospective study of 100 children aged 3 to 7 years was conducted. Logistic regression modeling and ROC analysis allow predicting a violation of the functional state of the cardiovascular system in children with tonsillitis syndrome. Risk groups for cardiovascular system failure were identified: cardiointervals (PNN50) below 10% and neurohumoral and metabolic levels (VLF) below 300 mc² (Se 65%, Sp 58%); IN at rest above 500 c.u. (Se 77%, Sp 77%), and bacterial etiology of tonsillitis syndrome (Se 77%, Sp 77%). An algorithm for monitoring this category of children is proposed.

Key words: tonsillitis syndrome, tonsillitis, cardiovascular system, heart rate variability, electrocardiography.
