摘要
本文报告65例冠心病患者先后进行24小时动态心电图监测并与冠状动脉造影对比分析。结果显示72例中冠状动脉狭窄>50%者29例,其中动态心电图监测心肌缺血阳性者22例,阴性7例,冠状动脉正常者36例,动态心电图检测心肌缺血阳性22例,阴性7例,冠状动脉正常者36例,动态心电图检测心肌缺血阳性7例,阴性29例,动态心电图检测心肌缺血的敏感性76%,特异性80%,预测准确性76%。陈旧性心肌梗死29例中动态心电图检测心肌缺血22例,真阳性20例,预测准确性76%,而36例可疑冠心病患者动态心电图检测心肌缺血阳性8例,其中真阳性2例,预测准确性仅25%。以上表明动态心电图检测心肌缺血的敏感性与准确性较高,在日常生活中应用24小时动态心电图检测是探讨早期心肌缺血变化的一个可靠及方便的方法。
the study investigated 65 patients with coronary heart disease undergoing 24-hour dynamic electrocardiogram and contrasted the result with coronary arteriography (CAG). The results showed that there are 29 patients whose stenosis ratio of coronary artery is over 50% and 36 patients whose coronary artery is normal. Using dynamic electrocardiogram monitoring myocardial ischemia, the sensitivity is 76%, the specificity is 80% and prediction accuracy is 76%. In 29 patients with old myocardial infarction, there are 22 patients with myocardial ischemia monitoring by dynamic electrocardiogram and 20 patients is true positive, the prediction accuracy is 76%. However, in 36 patients with suspectable coronary heart disease, there are 8 patients with positive myocardial ischemia monitoring by dynamic electrocardiogram and only 2 patients is true positive, the prediction accuracy is only 25%. Above showed that the sensitivity and accuracy of monitoring myocardial ischemia by dynamic electrocardiogram is comparatively high and it is a reliable and convenient method to monitor the change of early myocardial ischemia by 24-hour dynamic electrocardiogram.
