CAUSES OF SYNCOPAL CONDITIONS IN YOUNG SUBJECTS

Abstract

112 patients were studied to evaluate the incidence of syncopal conditions caused by impaired cardiovascular regulation in young subjects. Complex evaluation has found hyperventilation syndrome to be the reason for syncopal conditions in 8.9 %, vasopressor syncopal conditions in 13.4 %, reflex in 16.1 %, postural hypertension in 13.4 %, «hypersensitive» carotid sinus syndrome in 5. 4 %; whereas the cause of syncopal conditions remained undetermined in 42.8 % patients.
