Journal of Applied Clinical Pediatrics 2006;0(13):-
Objective To study the feature of the etiology of pediatric syncope by cases study,and to discuss the feasibility on identification between the cardiac and neurally-mediated syncope with its inducements and symptoms.Methods One hundred and eleven patients were etiologically classified by standard diagnostic procedure to summarize the inducements,presymptoms and symptoms.The data about cardiac and neurally-mediated syncope were statistically treated to find their characteristic manifestation.Results Among these,60.4% was non-cardiovascular syncope,18.9% was postural hypotension,18.0% was vasovagal syncope and 9% was cardiac syncope.Most of them were non-cardiac syncope and neurally-mediated syncope was on the top,while cardiac syncope was rare in children.Prolonged standing and nausea was the feature of the neurally-mediated syncope,and the cardiac syncope is associated with physical exercise.Conclusions Most pediatric inpatients were non-cardiovascular syncope in which neurally-mediated syncope is first on the list.The movement-related syncope is the feature of the cardiac syncope.The prolonged standing and nausea are due to neurally-mediated syncope.
