Study of the clinical significance and diagnostic standard of frequency-domain correlation cardiogram on coronary heart disease

目的 研究频谱心电图对冠心病的临床意义及诊断标准探讨。方法 随机分为冠心病组 10 0例 ,正常对照组 10 0例。两组病例均检测频谱心电图。结果 分级诊断法 :冠心病组阳性 92例 ,对照组阳性 10例。两组比较 (χ2 =134.5 5 ,P <0 .0 1)。单项自功率谱诊断法 :冠心病组阳性 89例 ,对照组阳性 10例。两组比较 (χ2 =12 4 .8,P <0 .0 1)。分级诊断冠心病组阳性92例 ,与单项自功率谱诊断冠心病组阳性 89例比较 (χ2 =0 .3,P >0 .0 5 )。结论 频谱心电图对冠心病的诊断敏感性高 ,假阳性少 ,对缺血性心脏病的早期诊断有一定的临床意义。在诊断的标准上 ,本研究结果单项自功率谱诊断法与分级诊断法无显著性差异 ,所以单项自功率谱诊断可作为冠心病独立诊断标准。

Objective To study the clinical significance and diagnostic standard of frequency-domain correlation cardiogram (FCG) on coronary heart disease (CHD).Methods The patients were randomly divided into control group 100 and CHD group 100.FCG was measured in two group.Results By normal grading diagnostic methods ,there were 92 positive in CHD group and 10 positive in control group(χ 2=134.55,P<0.01),By diagnostic methods of single/autopower spectrum,there were 89 positive in CHD group and 10 positive in control group,(χ 2=124.8,P<0.01).There was no differentce between normal grading diagnostic methods and diagnostic methods of single/autopower spectrum (χ 2=0.3,P>0.05).Conclusion FCG has a higher sensitivity and lower false postitive rate in CHD diagnostic has clinical significance in the early diagnosis of ischemic heart disease.There's no difference between single/autopower spectrum and the normal diagnostic methods .
