[A 24-hour profile of arterial pressure: vegetative regulation in persons with isolated systolic arterial hypertension]. / Sutochnyi profil' arterial'nogo davleniia i osobennosti ego vegetativnoi reguliatsii u lits s izolirovannoi sistolicheskoi arterial'noi davleniei.

A total of 117 persons were studied: 60 patients with isolated systolic arterial hypertension (ISAH) (22 males, 38 females; mean age 68.7 +/- 4.2 years), 22 males with ISAH (mean age 20.1 +/- 2.7 years), 15 healthy elderly subjects and 20 healthy young males. The analysis of heart rhythm variability and the results of 24-h arterial pressure monitoring specified an individual 24-h profile of arterial pressure and effects of vegetative regulation on this profile.
