头胸导联心电图诊断冠心病的价值

Diagnostic value of head chest lead ECG on coronary heart disease

目的 :比较 Wilson导联心电图 (常规 ECG)和头胸导联心电图 (HCECG)对冠心病的诊断价值。方法 :在 14 3例经选择性冠状动脉造影 (CAG)患者中 ,确诊的冠心病患者 12 9例 .分别使用常规心电图机和头胸导联心电图机非同步记录常规 ECG和 HCECG图形 ,由专业人员盲法分析其结果 ,评价二种方法对冠心病的诊断价值。结果 :常规 ECG诊断冠心病的灵敏度、特异度和准确度分别为 5 9% ,5 7% ,5 7%。HCECG诊断冠心病的灵敏度、特异度和准确度分别为 79% ,5 0 % ,76 %。HCECG均显著高于常规 ECG(P<0 .0 1)。结论 :HCECG对冠心病的诊断价值明显高于常规 ECG。

AIM:To compare the diagnostic value of electrocardiogram (ECG) and head chest lead electrocardiogram (HCECG) for coronary heart disease (CHD). METHODS: In 143 patients, there were 129 CHD patients who were confirmed by coronary angiography. Changes of morphology of ECG and HCECG were recorded and analyzed by specialist. Diagnostic value of two electrocardiographic methods was evaluated. RESULTS: Sensitivities of ECG and HCECG were respectively 59%,79%; specificity were respectively 57%,50%; and accuracy were respectivily 57%,76%. Sensitivity,Specificity and accuracy of HCECG were significantly higher than that of ECG. ( P <0.01,respectively). CONCIUSION: HCECG is a more valuable diagnostic method for CHD.
