[Increased predisposition to syncope in vasovagal syncope].
For revealing body peculiarities causing a heightened predisposition to vasovagal syncopes the somatic and neurological status, the general and cerebral hemodynamics, the person's psychological peculiarities, the brain bioelectric activity, changes in catecholamine metabolism, and in adrenocortical function were examined in 131 patients. As a result, factors determining the heightened predisposition to vasovagal syncopes were revealed, and a scheme was drawn which illustrated the development of a vasovagal syncope and the participation of the above factors in the pathogenetic mechanisms of the syncope at its different stages.
