心电图在冠心病中的诊断价值

Diagnostic value of electrocardiogram in coronary heart disease

目的:探讨分析心电图在冠心病检查中的诊断价值.方法:随机选择120例冠心病患者作为实验组,同时选择40例健康人群作为对照组进行本项研究,对实验组和对照组患者之间的各波段的异常情况进行统计分析,并对冠状动脉造影和心电图的检查结果进行比较分析.结果:研究结果显示,实验组的病理性Q波的出现率显著高于对照组,两组比较差异显著(P<0.05);实验组的心电图正常率也显著低于对照组,两组比较差异显著(P<0.05).而实验组的ST段下移率和T波倒置率和对照组之间没有显著差异(P>0.05).同时,冠状动脉造影阳性率和心电图阳性率间没有显著差异(P>0.05).结论:在进行冠心病诊断过程中,心电图具有重要的意义,因此,值得临床推广应用.

AIM： To investigate the diagnostic value of electro- cardiogram （ECG） in coronary heart disease. METHODS： A to- tal of 120 patients with coronary heart disease were randomly se- lected as the observation group, and 40 cases of healthy people as the control group. Abnormal situation of each band were statistically analyzed between the two groups, and results of coronary an- giography and electrocardiogram （ECG） were compared. RESULTS： It showed that, the incidence of pathologic Q wave of the observation group was significantly lower than that of the con- trol group, with statistically significant difference （P 〈 0.05 ）. The normal rate of ECG were also significantly lower than that of the control group, with statistically significant difference （P 〈 0.05）. There was no significant difference between the ST segment depression and T wave inversion rates of the two groups （P 〉 0.05）. Also, there was no significant difference between the positive rate of coronary angiography and ECG of the two groups （P 〉 0.05 ）. CONCLUSION ： The ECG is of vital significance in diagnosing coronary heart disease, and it is worthy of clinical application.
