Objective:To investigate the relationship between electrocardiogram QT dispersion changes and the degree of hypoxia in neonates with asphyxia.Method:From June 2012 to June 2015,100 cases of neonates in our hospital were selected as the research objects,they were divided into control group of 30 cases and experimental group of 70 cases according to whether or not choking symptoms,the experimental group was divided into group A of 40 cases and group B of 30 cases by Apgar score,the levels of creatine kinase isoenzyme (CK-MB)among three groups were detected,the change of QT dispersion was analyzed according to the results of ECG detection.Result:The CK-MB content and ECG QT dispersion of the experimental group A were significantly higher than the control group,the CK-MB content and QT dispersion of the experimental group B were significantly higher than the experimental group A,the differences were statistically significant(P<0.05).Conclusion:The higher degree of hypoxia,the higher level of creatine kinase isoenzyme and ECG QT dispersion are also higher, detect neonatal QT dispersion is able to assess the neonatal hypoxia,it is conducive to the early diagnosis and treatment of children's disease.%目的：探讨新生儿窒息后心电图QT离散度改变与缺氧程度之间的关系。方法：选取2012年6月-2015年6月于本院出生的新生儿100例，根据有无窒息症状分为试验组70例和对照组30例，采用Apgar评分将试验组分为试验A组40例和试验B组30例。分别检测三组新生儿的肌酸激酶同工酶（CK-MB）含量，并根据心电图检测结果分析QT离散度改变情况。结果：试验A组患儿的CK-MB含量和心电图QT离散度均明显高于对照组，试验B组患儿的CK-MB含量和QT离散度均明显高于试验A组，比较差异均有统计学意义（P<0.05）。结论：新生儿窒息后缺氧程度越重则CK-MB含量越高，心电图QT离散度亦越高，检测新生儿的QT离散度能够对新生儿的缺氧情况进行评估，有利于患儿病情的早期诊断与治疗。
