摘要
探讨心电图QT间期、QT离散度 (QTd)与冠状动脉病变及其程度和范围的关系。分析 138例行选择性冠状动脉造影病例的临床及心电图资料 ,观察不同程度和范围的冠状动脉病变对QT指标的影响。结果 :无冠状动脉狭窄病人的QTd为 42 .0± 18.2 4ms,单支病变组及多支病变组的QTd分别为 48.42± 17.11,5 9.15± 2 2 .75ms ,P均 <0 .0 5 ;轻度狭窄组及重度狭窄组的QTd分别为 48.6 7± 2 0 .45 ,5 8.12± 2 1.6 1ms ,P均 <0 .0 5。结论 :QTd延长有助于心肌缺血的诊断 。
To find out the relationship between QT parameta and the abnormality of extent and range of coronary artery.Methods:This retrospective study was performed on 138 patients who underwent coronary angiography(CAG )examination,in which the CAG data and ECG data were studied to observe how did QT peremeta change with coronary disease.Results:QT dispersion(QTd) in the group with no coronary disease was 42.0±18.24 ms,while in one vessel disease group and multiple vessel disease group were 48.42±17.11 and 59.15±22.75 ms, P<0.05 ,respectively.In light narrowing group and in severe narrowing group the QTd were 48.67±20.45 and 58.12±21.61ms, P<0.05 ,respectively.Conclusion:QTd helps to reflect myocardial ischemia,and maybe reflect the severity and range of coronary artery disease.
