摘要
目的比较心电图、高频心电图和运动平板试验对冠心病的诊断价值。方法针对冠心病组68例和对照组40例,进行心电图、高频心电图和运动平板试验,统计分析三者的诊断结果。结果 HFECG的敏感性大于ECG(χ2=6.81,P<0.05)及TET(χ2=12.17,P<0.05),但ECG与TET的敏感性差异无统计学意义(P>0.05)。TET的特异性大于心电图(χ2=5.23,P<0.05)及HFECG(χ2=5.61,P<0.05),ECG的特异性高于HFECG,但两者的差异无统计学意义(P>0.05)。结论高频心电图能提高敏感度,运动平板试验能提高特异性,而ECG的敏感性和特异性都处于相对平衡的水平。
Objective To compare the diagnostic value of electrocardiogram and high frequency electrocardiogram as well as treadmill exercise test in the diagnosis of coronary heart disease. Methods Coronary heart disease group 68 cases and control group 40 cases were given electrocardiogram and high frequency electrocardiogram as well as treadmill exercise test, the diagnosis were statistically analyzed among them. Results The sensitivity of HFECG was higher than ECG （χ2=6.81, P 0.05） and TET （χ2=12.17, P 0.05）, but the difference between ECG and TET were obvious （P 0.05）. The specificity of TET was higher than ECG （χ2=5.23, P 0.05） and high frequency ECG （χ2=5.61, P 0.05）. The specificity of HFECG were higher than electrocardiogram, but the difference was not significant （P 0.05）. Conclusion HFECG can improve the sensitivity; TET can improve specificity; The sensitivity and specificity of ECG were in a relatively balanced level.
