摘　　要：儿童及青少年直立不耐受(OI)存在自主神经功能异常。自主神经与心血管系统密切相关,自主神经功能异常可引起心电学指标变化。心电学指标包括心率变异性(HRV)、心室晚电位(VLP)、P波离散度(Pd)、QT间期离散度(QTd)、Tp-Te间期等。现就儿童及青少年OI心电学研究进展进行综述。Children and adolescents with orthostatic intolerance(OI)have autonomic nervous dysfunction.The autonomic nervous system is closely related to the cardiovascular system,and autonomic nervous dysfunction can cause changes in electrocardiographic(ECG)indexes,including the heart rate variability(HRV),ventricular late potential(VLP),P wave dispersion(Pd),QT interval dispersion(QTd),T peak-T end interval and etc.In this paper,the recent research progress on the electrocardiogram changes of OI in children and adolescents is reviewed.
