ABSTRACT

Objectives To analyze and compare the clinical features of autonomic nervous mediated syncope (NMS) and pseudo psychogenic syncope (PPS) in children.Methods Clinical features were retrospectively analyzed in children with syncope complaint not caused by cardiac syncope, situation of syncope, drug-induced syncope, and neurogenic and metabolic diseases that caused brief loss of consciousness, and the clinical features of similarities and differences between NMS and PPS were compared. Results In 106 children with syncope were included, there were 85 cases (80.2%) of NMS, 13 cases (12.3%) of PPS, and 8 cases (7.5%) of unexplained syncope. PPS was induced by recent mental stimulation; the syncope was more frequent; the score of orthostatic intolerance was higher; the omen was rare; the duration of attack was longer. NMS was induced by long time standing, movement and body position change; the omen was mainly dizziness, blurred vision and gastrointestinal symptoms; the duration of attack was short (<5 min).Conclusions NMS is the most common cause of syncope in children, while PPS is an important cause of transient consciousness of non-syncope. There are similarities in clinical features between NMA and PPA and differential diagnosis is needed.

ABSTRACT

Objective To analyze the spectrum of underlying diseases in children with transient loss of consciousness (TLOC) through a multi-center and large sample clinical research.Methods Nine hundred and thirty-seven children with TLOC who came from Beijing,Hunan province,Hubei province and Shanghai of China from Aug 1999 to Apr 2011 were recruited in the present study,and then the spectrum of underlying diseases in children with TLOC was analyzed.Results In 937 children with TLOC,903 cases (96.4% )were children with syncope,34 cases (3.6%) were non-syncope.And in 903 children with syncope,213 cases (23.6%) had vasovagal syncope (VVS) with vasoinhibitory response,46 cases (5.1% ) had VVS with cardioinhibitory response,112 cases ( 12.4% ) had VVS with mixed response,268 cases (29.7% ) had postural tachycardia syndrome,22 cases (2.4%) had orthostatic hypotension,19 cases (2.1% ) had situational syncope,21 cases (2.3% ) had cardiogenic syncope,and 202 cases (22.4% ) had unexplained syncope.Conclusion In children with TLOC,syncope was the most common underlying disease.And in children with syncope,the most common was VVS,followed by postural tachycardia syndrome.In three different hemodynamic patterns of VVS,the most common pattern was VVS vasoinhibitory pattern.
