Aim. To compare the effect of fosinopril and atenolol on synchronization of heart 0.1 Hz-rhythms and blood microcirculatory. Material and methods. 63 patients at the age of 47±8 with hypertension (HT) of grade 1-2 were enrolled in the study. 0.1 Hz-oscillations in heart rate variability (HRV) and in filling of microcirculatory bed were registered during passive tilt test under spontaneous breathing. The duration of each stage of test was 10 min. Synchronization was estimated as a phase difference between 0.1 Hz-rhythms of heart rate and filling of microcirculatory bed. Frequency values of HRV spectrum in LF- and HF-ranges were also assessed. Results. Fosinopril and atenolol showed comparable effect on blood pressure (BP) reduction. Atenolol decreased in heart rate significantly. Treatment with either fosinopril or atenolol in patients with significant vegetative dysfunction resulted in repair of functional interaction between heart 0.1 Hz-regulation and microcirculatory bed. Functional dissociation of 0.1 Hz-regulation mechanisms was observed under the treatment with fosinopril or atenolol in patients with initially sufficient interaction. Conclusions. Fosinopril and atenolol influenced similarly on heart 0.1 Hz-mechanisms and microcirculation autonomic regulation in patients with HT. Atenolol is a drug of choice in patients with sympathicotony. Both drugs should be administered in according with an individual level of 0.1-Hz rhythms synchronization assessed before start of the treatment.

Aim: to study dynamics of the 0,1Hz-componentofthe heart rate variability(HRV) spectrum in patients with arterial hypertension taking fosinopril and atenolol. 49 patients with hypertension were enrolled (age - 46+/-7 years). Fosinopril and atenolol were administered consequently. The power of 0,1 Hz-component of the HRV spectrum was assessed during a passive orthostatic test. Results: In patients taking fosinopril and atenolol comparable decrease of blood pressure was observed. Atenolol caused reliable decrease of a heart rate during orthostatic test. The power dynamics of 0,1Hz-componentwas comparable in patients taking fosinopril and atenolol. Conclusion: fosinopril and atenolol influenced similar on 0,1-Hz mechanisms of vegetative heart control system.
