Research progress on electrocardiogram changes of orthostatic intolerance in children and adolescents / 中华实用儿科临床杂志

ABSTRACT

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.
