[Preventive strategy for atrial fibrillation in arterial hypertension].

The aim of the study was to evaluate effectiveness and safety of angiotensin II receptor blockers and inhibitors of angiotensin-converting enzyme (ECE) for protective therapy following medicamentous cardioversion with propafen at a loading dose of 600 mg in patients with paroxysmal atrial fibrillation and arterial hypertension. 101 patients were divided in 2 groups. Group 1 included 75 patients who received ACE inhibitor lisinopril (10 mg BID) after recovery of sinus rhythm by propanorm.

The present epidemiological situation in diphtheria in the Republic of North Ossetia (Alania) is analyzed. The data on diphtheria morbidity and lethality are given. The present stable situation resulted from mass immunization of the adult population which ensured the level of vaccination coverage reaching 87% in 1995.

[Spectral analysis of the variability of heart rhythm in the analysis of changes in the autonomic regulation during treatment of hypertension with sodium chloride baths].

Changes in spectral parameters of heart rate variability were assessed in patients with mild and moderate hypertension (n = 48) and healthy subjects (n = 34) taking sodium chloride bath and in active orthostatic test before and after balneotherapy. Significant changes were not registered. The course of balneotherapy stimulated sympathetic or parasympathetic activity (relative enhancement occurred in 67, absolute in 15% versus 8 and 10% patients, respectively).
