RESUMO
Basic hemodynamic indices in aged 15-16 practically healthy adolescents do not differ essentially, but in patients with juvenile arterial hypertension is noticed their authentic rise in proper age groups. The correlation of body mass is marked with the basic hemodynamic parameters and likewise the indices of double production depend on systolic pressure and heart rate. In adolescents troubled with juvenile arterial hypertension is noticed intensification of sympathetic link of regulatory mechanisms of vegetative nervous system and unsatisfactory hypersympathetic reaction on orthostatic test which shows the total disbalance of the organism. The latter can be considered as one of the pathologic aspects of development of juvenile arterial hypertension; on the other hand non-invasitive investigation of functional state of vegetative nervous system maybe recommended for inclusion in the project of preventive medical practice to early revealing juvenile arterial hypertension or its predisposition to it.
