摘　　要：目的探讨碎裂QRS波对冠心病心肌缺血的诊断价值。方法选取常规体表心电图有碎裂QRS波的患者30例,心电图正常者40例,患者均行平板运动试验和冠状动脉血管造影。结果两组平板运动试验阳性例数和冠状动脉血管造影异常数均有明显差异(p<0.05),在碎裂QRS波组阳性患者明显高于正常组。结论碎裂QRS波可作为判断冠心病心肌缺血的标志之一。Objective To investigate the value of fragmented QRS complex in the diagnosis of coronary heart disease.Methods Treadmill exercise test was performed in 30 cases of conventional body surface electrocardiography(ECG)with fragmented QRS complex and 40 subjects with normal ECG.We compared the results of coronary angiography.Results There were significant differences in the number of positive cases of treadmill exercise test and abnormal angiography between the two groups(p<0.05).The number of positive cases in patients had fragmented QRS complex significantly higher than that in the normal group.Conclusions Fragmented QRS complex can be used as a marker of myocardial ischemia in patients with coronary heart disease.
