ELECTROENCEPHALOGRAM WITH VAGAL STIMULATION VALUE IN DISAUTONOMIC DISORDERS.
Abstract
A descriptive study of the Electroencephalogram with vagal stimulation (EEGmv) was carried out in the Clinical Neurophysiology Department of the CIREN, during the period 1999-2003. A total of 37 recordings were carried out, 24 were female and 13 male (21 children and 16 adults). The approach was done in a MEDICID 4 equipment Neuronic SA produced in Cuba with software for polygraphy recording Track Walker. The use of anaesthetic assistant was not required. 18 studies were positive (49%) and were compatible with vagal syncope diagnosis, while 19 of them were negative (51%). This approach was positive in 6 adults patient (37%) and negative in 10 patients (62%). On the other hand, in paediatric people age range (10-16 years), 9 had negative (43%) and 12 positive results (57%) with the appearance of bradicardy and/or asistoly. These results support the assumption that at this age there is a high frequency of vaso-vagals dysfunctions. We recommend doing right indication of this kind of stimulation in order to obtain the actual diagnostic of vaso-vagal syncope that is usually confused with other disorders.Downloads
