摘要

目的分析12导联心电图T波峰末间期（Tp-Te）及QT间期离散程度（QTd）与冠心病严重程度的相关性及对冠心病的诊断价值。方法回顾性分析50例健康体检者及50例冠心病患者的临床资料

以健康体检者为健康组

以冠心病患者为冠心病组

对比两组Tp-Te、QTd差异

分析Tp-Te、QTd与冠心病严重程度的相关性及对冠心病的诊断价值。结果冠心病组Tp-Te及QTd均高于健康组

差异存在统计学意义（p<0.05）。同时

冠心病组Tp-Te、QTd与冠状动脉狭窄程度均呈显著的正向直线相关性

存在统计学差异（p<0.05）。此外

在冠心病的诊断中

Tp-Te及QTd均具有着较高的灵敏性、特异性及准确性

且经分析

Tp-Te及QTd对冠心病均具有着显著的诊断价值（p<0.05）。结论 Tp-Te及QTd与冠心病严重程度存在显著的正向相关性

且对于冠心病具有显著的诊断价值。

Abstract

Objective To analysis the 12-lead electrocardiogram T wave period（Tp-Te） and at the end of the period between QT dispersion degree（QTd） and the correlation between the severity of coronary heart disease（CHD）and the value of the diagnosis of coronary heart disease. Methods A retrospective analysis of 50 cases of healthy physical examination and the clinical data of 50 patients with coronary heart disease

for health group by physical examination

in patients with coronary heart disease（CHD） for coronary heart disease group

compared two groups of Tp-Te

the difference of QTd

analysis of Tp-Te

QTd and correlation between the severity of coronary heart disease（CHD）

and value to the diagnosis of coronary heart disease. Results Tp-Te and QTd CHD group were higher than in healthy group

the difference is statistically significant（p<0.05）. At the same time

the group of Tp-Te

QTd and coronary heart disease of coronary artery stenosis degree has significant positive linear correlation

statistical differences（p<0.05）. In addition

in the diagnosis of coronary heart disease

Tp-Te and QTd has a higher sensitivity

specificity and accuracy

and through the analysis of Tp-Te and QTd value to the diagnosis of coronary heart disease have a significantly（p<0.05）. Conclusions There is significant positive correlation between Tp-Te and QTd and the severity of coronary artery disease

and it has significant value for the diagnosis of coronary heart disease.
