Clinical characteristics of vasovagal syncope and postural orthostatic tachycardia syndrome in children
摘要
Abstract
Objective To investigate the clinical evidence for differential diagnosis between vasovagal syncope (VVS) and postural orthostatic tachycardia syndrome (POTS) in children. Methods Forty children [aged 6- 18 yrs. median (11.8 ± 2.9) yrs] who were diagnosed with VVS and 165 children [aged 5 - 19 yrs, median (11.4 ±2.7) yrs] who were diagnosed with POTS in the clinics of Peking University First Hospital from March 2009 to April 2011 were recruited in the study. History-taking,including clinical manifestation, family history, life style, physical examination, standing test and head-up tilt test, etc, was done for each patient. Clinical characteristics of VVS and POTS in children were summarized by comparing the two groups. Results There were some similar characteristics between VVS and POTS. Both VVS and POTS were usually at school-age or adolescent period. Their symptoms mostly occurred in summer and autumn. Most patients had trigger of symptoms and presyncope symptoms. Moreover, most patients had complaint after the episodes. The symptoms would be relieved when supine in most patients. The frequence of syncope was higher in the children with VVS than those with POTS (P < 0.001), while the frequence of dizziness was higher in the children with POTS than those with VVS (P < 0.001). The percentage of patients whose fathers have a family history of orthostatic intolerance in children with VVS was higher than that of children with POTS (P < 0.05). Conclusion Head-up tilt test is an important and objective examination in differential diagnosis between VVS and POTS in children. The frequence of syncope and dizziness could be used as a reference indication to help differentiate diagnosis between VVS and POTS.关键词
