Introduction: One of the effective methods in patients with arterial hypertension (AH) treatment is dynamic electro nervous stimulation (DENS). DENS is a new method of transcutaneous electronerve stimulation (TENS), consisting short electric impulses influence on reflexogenous zones. The form of these impulses is constantly reacting on change of skin resistance in subelectrode zone. However the mechanisms of hypertensive effect of DENS are not sufficiently investigated. The purpose of the research is estimation of DENS efficiency in patients with an initial stage of AH.
Patients and Methods: Two groups of patients (12 persons in each group) with the first stage of АH and not more than second group of risk were included in study. The first group was treated by DENS without any medicines during 10 days. The second one was a control group. Daily monitoring of electrocardiogram (ECG) with rhythm of heart variability (RHV) studying and arterial pressure (AP) was performed in both groups before and after treatment.
Besides an endothelial functions by duplex scanning of brachial artery with reactive hyperemia test and quality of life by questionnaire SF-36 were investigated.
Results: Significant decrease of daily systolic AP from 132,5±13,2 mm Hg to 124,3±19,1 mm Hg (р=0,034) and maximal daily heart rate from 143,0±10,7 to 133,1±9,2 (p=0,028) was shown. The analysis of vegetative status performed by RHV showed reduction of sympathetic nerve system tonus and increase of parasympathetic tonus. The results estimation of reactive hyperemia test showed significant increase of brachial artery diameter (р=0,011). Quality of a life index had significant tendency to improvement.
Conclusion: DENS exerts significant hypotensive affect in patients with initial stage of arterial hypertension. Vegetative status of hypertensive patients has a tendency to normalization. DENS improves quality of live.
