[Variability of cardiac rhythm in patients with a symptomatic renal hypertension and effect of ramipril on its changes].

Variability of cardiac rhythm and influence of Ramipril on it have been studied in 31 patients with a secondary renal hypertension of 1 and 2 stages. Obtained data have shown, that treatment with Ramipril normalizes neurohumoral regulation at the expense of decrease of excessive sympathetic stimulation and decrease of peripheral parasympathetic insufficiency rate. All above mentioned changes were accompanied by reduction in frequency and grade of blood pressure increase and improvement in tolerance to physical activity.
