【摘要】 目的评价心向量图对陈旧性心肌梗死的诊断价值。方法选择陈旧性心肌梗死患者72例(观察组),非心肌梗死患者32例作为对照组,顺序记录12导联心电图及心向量图,计算并比较两者诊断的敏感性、特异性和准确性。结果心向量图和心电图对陈旧性心肌梗死的诊断敏感性分别为98.61%和48.61%、准确性分别为97.12%和61.54%,差异均有非常显著性意义(P<0.01);特异性均为90.63%,差异无显著性意义(P>0.05)。结论心向量图对陈旧性心肌梗死有较高的诊断价值,可降低误诊率和漏诊率。更多还原

【Abstract】 Objective To evaluate the value of vectorcardiogram in the diagnosis of old myocardial infarction(OMI).Methods 12-lead electrocardiogram(ECG)and vectorcardiogram were recorded and analyzed in 72 OMI patients(OMI group)and 32 patients without myocardial infarction(control group).Calculate the sensitivity, specificity and accuracy of the two methods.Results The sensitivity of vectorcardiogram and ECG in the diagnosis of OMI was 98.61% and 48.61%, and the accuracy was 97.12% and 61.54%, respectively.There were significant differences in the sensitivity and accuracy between vectorcardiogram and ECG(P < 0.01).The specificity of both methods was 90.63%.Conclusion Vectorcardiogram is of great value in identifying OMI and avoiding misdiagnosis.更多还原
