超声心动图Z值在儿童心脏疾病诊疗中的应用进展

Application progress of echocardiography Z scores in diagnosis and treatment of pediatric cardiac disease

儿童先天性心脏病、后天获得性心脏病、心肌病中,对儿童心脏结构、大小和功能的评价是决定治疗方案和判断预后的重要因素。传统的超声心动图常以个体的心脏测量绝对值来评估心脏的结构和功能变化,对处于生长变化的儿童,则易造成判断偏倚。Z值将超声心动图测量结果经体表面积标准化转换,从统计学方法上寻求解决办法。本文就超声心动图Z值在儿童心脏疾病诊疗中的应用进展进行综述。

In children with congenital heart disease,acquired heart disease and cardiomyopathy,evaluation of cardiac structure and function of children is an important factor in determining treatment options and prognosis.Traditional echocardiography often evaluate the cardiac structure and function by measuring the absolute values of the individual heart.But it is easy to cause judgment bias for the growth children.The question can be solved with a statistical method by converting the echocardiographic measurements into the Z scores through body surface area standardization.This article reviews the application progress of echocardiography Z scores in pediatric cardiac disease diagnosis and treatment.
