Abstract:
Postural tachycardia syndrome (POTS) is one of the main hemodynamic types of nerve-mediated syncope in children and adolescents, mainly manifested with orthostatic intolerance symptoms, and an excessive increase in heart rate from the supine position to the upright position.The current main treatments of POTS include non-drug therapies (health education, autonomic nervous function exercise, and the intake of water and salt) and drug therapies (α-adrenergic receptor agonists and β-adrenergic receptor blockers). Hemodynamic parameters and biomarkers have a good effect on the diagnosis and prognosis estimation of POTS.Heart rate and blood pressure are one of the basic vital signs that are readily available clinically.In this review, the prognostic value of heart rate and blood pressure in children and adolescents with POTS are evaluated.
