摘要
目的探讨心电图ST段水平延长临床诊断冠心病的价值。方法选取具有典型或不典型心绞痛史,且经冠状动脉造影确诊为冠状动脉粥样硬化性心脏病(即冠心病)的患者33例为观察组,及同期收治具有典型或不典型心绞痛史,但经冠状动脉造影正常患者39例为对照组,观察并对比两组患者心电图ST段变化。结果观察组心电图ST水平延长超过0.12s的患者29例(87.9%),对照组ST段水平延长超过0.12s的患者9例(23.1%),两组相比差异有统计学意义(P<0.01);ST段水平延长诊断冠心病敏感性为87.9%,特异性为76.9%,阳性预测值为76.3%,阴性预测值为88.2%。结论冠心病患者ST段水平延长超过0.12s的概率显著高于非冠心病患者,ST段水平延长可以作为一个冠心病诊断的简便、有效指标。
Objective To explore the clinical diagnostic value of prolongation of horizontal ST segment duration for coronary heart disease.Methods Thirty-three cases of patients with coronary heart disease were chosen as observation group,while 39 cases of patients hospitalized in the same period were chosen as control group.All the 72 patients were with angina pectoris history which horizontal ST segment duration of the electrocardiogram were observed and compared.Results Twenty-nine cases （87.9%） of ST segment prolongation surpassed 0.12 s were found in observe group,while only 9 cases of ST segment prolongation surpassed 0.12 s were found in control group,and there was significant difference be tween two groups （P0.01）;The sensitivity for prolongation of horizontal ST segment duration to diagnose coronary heart disease was 87.9% wihle the specificity was 76.9%,and the positie predictie alue was 76.3% while the negatie predictie alue was 88.2%.Conclusion Patients with coronary heart disease has higher rate of horizontal ST segment duration prolonging over 0.12 s and diagnosing coronary heart disease on the base of horizontal ST segment duration prolongation is an effective clinical methods.
