Pulsometric study of the functional state of cardiovascular system under conditions provoking neurogenic syncopes.
The effects of passive and active orthostatic loads on the amplitude and temporal parameters of pulse waves were studied using an original computer assisted method of differential sphygmomanometry. Changes in the cardiac rhythm reflecting impairment of the autonomic regulation of the circulatory system and preceding neurogenic cardiovascular syncope were revealed and evaluated. Comparative analysis revealed similarity between these changes under conditions of both passive and active orthostasis, which confirmed the diagnostic value of differential sphygmomanometry.
