Orthostatic reactions of systolic arterial pressure in patients with stable atrial fibrillation
Yu. A. Chernaya , L. A. Martimianova , N. I. Yabluchansky

The association between various types of orthostatic reactions (OR) of systolic arterial pressure
(SAP) and clinical manifestations of stable atrial fibrillation was investigated in elderly pati-
ents. All types of OR of SAP with prevailing isotensive ones were observed in these patients. Hy-
potensive SAP OR were more frequent in old patients with severe arterial hypertension, isotensive 
in elderly patients with left ventricle ejection fraction < 40%.
Key words: orthostatic reactions (OR) of systolic arterial pressure, hypotensive, isotensive, hy-
pertensive OR, atrial fibrillation, clinical manifestations.
