Abstract：Objective To investigate the incidence and clinical characteristics of orthostatic hypertension (OHT) in children.Methods Totally 1348 children with syncope,dizXziness,erc,were collected in Peking University First Hospital between 2009 and 2015,24 of whom were diagnosed with OHT.Demographic characteristics,the occurrence frequency of various clinical manifestations and its inducing factors,course of disease and the changes of the blood pressure at the lying position were analysed.Results (1)Among 1348 children,OHT was in 24 (male 14,female 10).The case proportions of those at or under 12 years old to those beyound 12 years old and the ratio of male to female showed no significant differences.(2)There was no difference between those at or younger than 12 years old and those older than 12 years old (x2 =0.411,P=0.521),or the ratio of males to females in sOHT and dOHT.(3)The most common clinical manifestations were syncope,dizziness,chest tightness,and so on.Syncope and chest tightness mostly appeared in dOHT children.The incidence of dizeiness in sOHT and dOHT was similar.In children,common inducements were sudden postural changes (from supine to upright and standing position) (41.7％),persistent standing (37.5 ％),or persistent seating (37.5％).Persistent standing and persistent seating were the main cause of sOHT.Sudden postural changes were the main cause of dOHT.Conclusion There is no age or gender difference in the incidence and typing of OHT in children.Syncope,dizziness and chest tightness are the main clinical manifestations.Persistent standing and persistent seating are the main cause of sOHT.Sudden postural changes are the main cause of dOHT.
