METHOD FOR CHOOSING OPTIMAL THERAPY OF PATIENTS WITH ORTHOSTATIC SYNCOPE

摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, particularly cardiology. Passive orthostatic test involves measuring: mean arterial pressure by the end of the 1^st minute of orthostasis, mm Hg, APm._1; a reaction of total peripheral vascular resistance (TPVR) by the end of the 1^st minute of orthostasis as related to the prone value, %, %TPVR; a reaction of basic thoracic impedance by the end of the 1^st minute of orthostasis as related to the prone value, %, %BI; a reaction of standard power of rhythmogram spectrum low frequency by the end of the 1^st minute of orthostasis as related to the prone value, %, %LFn. An integral 'orthostatic stability' (IOS) is determined: IOS=3.83APm._1+0.98(%TPVR)+14.4(%BI)+0.954(%LFn) wherein 3.83APm._1 is a pressure index; 0.98(%TPVR) is a vasoconstriction index; 14.4(%BI) is a blood redistribution index; 0.954(%LFn) is a vegetative control index. The derived values of IOS, the pressure index, the vasoconstriction index, the blood redistribution index and the vegetative control index are used to choose the optimal therapeutic method.;EFFECT: method enables selecting the optimal therapy for the patients taking into account the pathogenetic aspects.;1 tbl, 2 ex
