心电图对陈旧性心肌梗死的诊断价值及漏诊原因分析

Analysis of the diagnostic value and missed diagnosis of old myocardial infarction electrocardiogram

目的:探讨心电图对陈旧性心肌梗死的诊断价值以及其漏诊的原因,为临床合理利用心电图提供理论依据。方法:收治陈旧性心肌梗死患者80例为研究组,对其临床资料进行回顾性分析,另收治非心肌梗死患者80例为对照组,两组患者均采用心电图进行检测并记录12导心电图数据、图形,探讨心电图对陈旧性心肌梗死诊断的准确性、特异性以及敏感性。结果:心电图对陈旧性心肌梗死诊断的准确性、特异性以及敏感性分别是63.13%、70%、56.25%,在冠脉病变程度上诊断正确和漏诊患者之间差异有统计学意义(P<0.05)。结论:心电图对陈旧性心肌梗死的诊断的特异性高,但是敏感性及准确性都较低,易出现漏诊状况,造成漏诊的原因与冠脉病变程度密不可分。

Objective:To discuss the diagnostic value and missed diagnosis of old myocardial infarction electrocardiogram,to provide a theoretical basis for clinical rational use of electrocardiogram.Methods:80 patients with old myocardial infarction were selected as the research group.80 patients with non-myocardial infarction were selected as the control group.Two groups of patients with ECG were detected and recorded 12 lead ECG data,graphics,investigating the electrocardiogram on old myocardial infarction diagnosis accuracy,specificity and sensitivity.Results:Electrocardiogram in old myocardial infarction diagnosis accuracy, specificity and sensitivity were 63.13%,70%,56.25%.The correct diagnosis group and the misdiagnosis group had statistically significant difference between the degree of coronary artery disease (P<0.05).Conclusion:The specificity of ECG diagnosis of old myocardial infarction is high,but the sensitivity and accuracy are low.Proning to misdiagnosis condition,causing the misdiagnosis reasons and the severity of coronary artery disease are closely related.
