Objective: To explore the clinical characteristics of children with orthostatic intolerance(OI), strengthen the understanding of OI, and improve the level of diagnosis and treatment of OI.#br# Methods: A retrospectiveanalysis of 102 cases of orthostatic intolerance was conducted, who were treated from January 2018 to December 2019 in the Maternal and Child Health Hospital of Inner Mongolia Autonomous Region to explore the clinical characteristics of orthostatic intolerance. Among them, 62 children with orthostatic intolerance confirmed by HUTT were included as the observation group, and 40 children with negative HUTT were included as the control group.#br# Results: In 62 cases of OI, 43 cases (69.4%) were VVS, 17 cases(27.4%) were POTS and 2 cases(3.2%) were OHT. Among the 62 cases, 55 cases(88.7%) had induced factors, including 20 cases(32.2%) of longterm standing, 17 cases(27.4%) of posture change, 14 cases(22.6%) of strenuous exercise. Among the 62 cases,52 cases(83.8%) had precursory symptoms in head-up tilt test(HUTT). The common manifestations were dizziness in 33 cases(53.2%), chest tightness in 24 cases(38.7%), palpitation in 23 cases(37.1%), and color change in 23 cases(37.1%). Arrhythmias were found in all OI children, including 55 cases(88.7%) of sinus tachycardia and 13 cases(21.0%) of sinus bradycardia.#br# Conclusion: The main inducing factors of OI are standing for a long time, body position change, etc., and the main precursory manifestations are dizziness, chest pain, palpitation, etc.

Abstract: Objective: To explore the clinical characteristics of children with orthostatic intolerance(OI), strengthen the understanding of OI, and improve the level of diagnosis and treatment of OI.
Methods: A retrospectiveanalysis of 102 cases of orthostatic intolerance was conducted, who were treated from January 2018 to December 2019 in the Maternal and Child Health Hospital of Inner Mongolia Autonomous Region to explore the clinical characteristics of orthostatic intolerance. Among them, 62 children with orthostatic intolerance confirmed by HUTT were included as the observation group, and 40 children with negative HUTT were included as the control group.
Results: In 62 cases of OI, 43 cases (69.4%) were VVS, 17 cases(27.4%) were POTS and 2 cases(3.2%) were OHT. Among the 62 cases, 55 cases(88.7%) had induced factors, including 20 cases(32.2%) of longterm standing, 17 cases(27.4%) of posture change, 14 cases(22.6%) of strenuous exercise. Among the 62 cases,52 cases(83.8%) had precursory symptoms in head-up tilt test(HUTT). The common manifestations were dizziness in 33 cases(53.2%), chest tightness in 24 cases(38.7%), palpitation in 23 cases(37.1%), and color change in 23 cases(37.1%). Arrhythmias were found in all OI children, including 55 cases(88.7%) of sinus tachycardia and 13 cases(21.0%) of sinus bradycardia.
Conclusion: The main inducing factors of OI are standing for a long time, body position change, etc., and the main precursory manifestations are dizziness, chest pain, palpitation, etc.
