摘要
目的:常规12导联平静心电图中碎片状QRS复合波的出现,具有诊断陈旧性心肌梗死的意义。本研究发现fQRS波也可见于冠心病心肌缺血心电图中,故认为fQRS波是提示心肌缺血的一种标志。方法:随机选取2008~2009年作者单位心内科住院病房患者520名,并给予其心电图、平板运动及冠状动脉造影(CAG)等各项检查。假使平板运动、CAG、平板运动/CAG任一结果阳性为诊断心肌缺血的金标准,并依此来观察fQRS波在诊断心肌缺血时的意义。结论:fQRS在诊断心肌缺血方面有着较高的特异性和阴性预测值,其出现能够预测心肌缺血的存在。
Objective : Background and Objective The appearance of a fragmented QRS complexes (fQRS) on a resting 12 - lead electrocardiogram (EGG) was regarded as a marker of a prior silent MI. In our study ,we find that the fQRS was also appears in patients with myocardial i schemia. We, therefore, postulate that the fQRS may be a sign of myocardial ischemia. Methods:520 patients were selected randomly in our hospital,and were given ECG,CAG and exercise treadmill test. We use the exercise treadmill test, CAG, and exercise treadmill test and/or CAG as the gold standard of the myocaridal ischemia, and observe the value of fQRS in myocardial ischemia according to the gold standard. Conclusions:The fQRS has the high specificity and negative predictive value for myocardial ischemia. The presence of fQRS may denote the existence of myocardial ischcmia.
