本文分析115例冠心病、102例可疑冠心病和100例正常人共317例24小时连续心电监测结果,部分病例与活动平板测验和冠状动脉造影对比。检查结果冠心组63.5%有室早,74.8%出现缺血型ST-T 改变,与冠脉造影的符合率73.7%。105例同期进行了动态心电图和平板心电图检查,两项结果一致者76例(72.4%),敏感性和特异性前者分别为66.6%、81.2%,后者分别为60.8%、81.2%。两项联合检查,敏感性和特异性可提高到78.4%和93.7%,假阳性率和假阴性率可降至6.2%和21.6%。
This article analyzes 115 cases of coronary heart disease, 102 cases of suspected coronary heart disease and 100 normal subjects were 317 cases of 24-hour continuous ECG monitoring results, and some cases compared with the activity of the plate test and coronary angiography. The results of coronary heart disease 63.5% room early, 74.8% of ischemic ST-T changes, consistent with coronary angiography 73.7%. There were 76 cases (72.4%) in the 105 patients who had the same electrocardiogram and electrocardiogram. The sensitivity and specificity were 66.6% and 81.2% respectively, the latter were 60.8% and 81.2% respectively. The two combined tests increased the sensitivity and specificity to 78.4% and 93.7%, and the false-positive and false-negative rates to 6.2% and 21.6% respectively.
