摘要:
目的 比较体表电位标测(BSPM)、心电图(ECG) 和高频心电图(HFECG) 三种心电方法对冠心病(CHD) 的诊断价值。方法 使用BSPM-III 型体表电位标测微机系统, 对冠脉造影确诊的60 例CHD 患者和60 例正常人进行BSPM , 并分析T峰值图图形和极小值位置的变化。同时记录ECG和HFECG, 并由专业人员盲法分析其变化, 评价三种方法的诊断价值。结果 ECG, HFECG 和BSPM 诊断的敏感度分别为67% , 87%和85% , 特异度分别为63% , 75%和90% , 准确度分别为65% , 81%和88%。诊断的敏感度HFECG 和BSPM 均显著高于ECG (P<0.05) , 特异度HFECG 与ECG 无差别(P>0. 05) , 而BSPM 非常显著高于ECG (P<0. 01) , 也显著高于HFECG(P<0. 05)。结论 ECG 诊断CHD 的敏感度和特异度都较低, HFECG 能提高敏感度, 而BSPM 既能提高敏感度, 又能提高特异度,BSPM 是一种价值较高的CHD 诊断方法。
Abstract:
AIM To compare the diagnostic value of body surface potential mapping (BSPM) and electrocardiogram (ECG) and high frequency ECG (HFECG) for coronary heart disease (CHD ).METHODS BSPM was undertaken in 60 normals and 60 patients with CHD confirmed by coronary angiography using BSPM-III computer system. Changes of morphology and location of minimal values in T peak potential map were analyzed. ECG and HFECG were also recorded and analyzed by specialist. Diagnostic value of 3 electrocardiographic methods was evaluated.RESULTS Sensitivity of ECG, HFECG and BSPM was respectively 67% , 87% and 85% ,specificity was respectively 63% , 75% and 90% , accuracy was respectively 65% , 80% and 88%.Sensitivity of HFECG and BSPM was significantly higher than that of ECG. Specificity of HFECG and ECG was no significantly different (P>0. 05) , but that of BSPM was significantly higher than that of ECG (P<0. 01) and HFECG (P<0. 05) also. CONCLUSION The sensitivity and specificity of ECG to CHD are relatively low whereas HFECG can improve this sensitivity,and BSPM can improve not only the sensitivity and but also the specificity. Therefore, BSPM was a diagnostic method of higher value for CHD.
