摘 要: | 目的测定非ST段抬高型急性冠脉综合症患者的心电图QRS时间,通过与冠状动脉造影对比,判断其对左主干/三支病变诊断的指导作用。方法对比106例非ST段抬高型急性冠脉综合症患者的体表心电图QRS时间,并与冠状动脉造影结果比较。结果QRS时间和左主干/三支病变具有相关性(OR=904,P〈0.01),QRS时间/〉90ms预测左主干/三支病变的敏感性为88%,特异性为88%。结论QRS时间增宽可作为非ST段抬高型急性冠脉综合症患者左主干/三支病变的预测因子。

Abstract: | Objective To investigate QRS duration in the prediction of left main coronary disease or 3-vessel disease in patients with non-ST-segment elevation acute coronary syndrome (NSTE-ACS). Methods The QRS duration was measured on 12-lead electrocardiogram in 106 patients with NSTE-ACS and compared to the results of coronary angiography. Results QRS duration was correlated with left main coronary disease or 3-vessel disease (OR=9.04,P〈0.01). The sensitivity and specificity of QRS duration ≥90ms in identifying left main coronary disease or 3-vessel disease were 88% and 88%, respectively. Conclusion QRS duration prolongation may be a predictor of left main coronary disease or 3-vessel disease in patients with NSTE-ACS. |
