[Peculiarities of blood pressure rhythms and blood pressure variability in adolescents with hypertension (in accordance with twenty-four monitoring of blood pressure)].
Registration of 24-hour blood pressure in adolescents with and without hypertension revealed active participation of sympathetic nervous system in genesis of juvenile hypertension. Hypertension in adolescents was mainly systolic, blood pressure elevation as a rule was accompanied by accelerated heart rate and increased pulse pressure. Episodes of blood pressure elevations occurred mostly during day time. Desynchronization of 24-hour rhythms due to excessive nocturnal blood pressure lowering was found to be typical for this age group. More than two thirds of adolescents with episodes of blood pressure elevation had also 'white coat hypertension'.
