Prevalence of joint hypermobility, postural orthostatic tachycardia syndrome (POTS), and orthostatic hypotension in school-children

Abstract

Children with joint hypermobility, postural orthostatic tachycardia syndrome, and orthostatic hy-potension report autonomic symptoms such as dizziness, nausea, headaches, and palpitations. It is unclear if there is a pathophysiological link between connective tissue disorders and autonomic symptoms. There is no published data on the prevalence of disorder at the community level. Primary objective: To assess the prevalence of joint hypermobility, orthostatic hypotension, and postural or-thostatic tachycardia syndrome in children. Secondary objective: To determine the relationship between joint hypermobility, orthostatic hypotension, and postural orthostatic tachycardia syndrome. Patients and Method: Participants aged 10 to 18 years were selected from public schools in three Colombian cities. The surveys included historical questions on the incidence of dizziness, nausea, headache, tremor, blurred vision, vertigo, anxiety, near syncope and syncope, sweating, palpitations triggered by standing in the two months prior to the investigation. Each of these signs and symptoms.
