[摘要] 目的 探讨心电图碎裂QRS波与冠心病患者冠脉病变的相关性。方法 对126例明确诊断的冠心病患者冠脉病变情况进行评估，比较心肌各壁导联fQRS 波发生率并分析fQRS与冠脉病变范围和罪犯血管的相关性。结果 fQRS波在下壁的发生率明显高于前壁和侧壁，差异有统计学意义(P<0.05)。LAD和非LAD 病变、LCX 和非LCX 病变、RCA 及非RCA 病变各导联fQRS 波发生率比较，差异无统计学意义(P>0.05)。fQRs在多支病变患者的发生率与单支病变比较，差异无统计学意义(P>0.05)。结论 fQRS波在心电图下壁导联Ⅱ、Ⅲ和aVF的发生率较高，对冠心病诊断有预测价值。但心电图不同导联的fQRS 波不能明确定位罪犯血管病变支和判断冠状动脉病变支数。

[Abstract] Objective To explore the relationship between ECG leads on the fragmented QRS (fQRS) complexes and coronary artery lesion in patients with coronary heart disease. Methods All 120 patients with coronary heart disease were selected and their coronary lesions were evaluated. The occurrence of the fQRS complexes in anterior myocardium, lateral myocardium and inferior myocardium were compared. The relationships were studied between the fragmented QRS complexes and range of coronary lesions and culprit artery. Results The occurrence of the fQRS complexs in inferior myocardium was higher than those in anterior myocardium and lateral myocardium(P<0.05). There was no significant difference of the occurrence of fQRS complexs between anterior myocardium and lateral myocardium (P>0.05). There was no significant difference of the occurrence of fQRS complexs between LAD and non-LAD, LCX and non-LCX, and RCA and non-RCA pathological lesion. Conclusion The fragmented QRS complex in Ⅱ, Ⅲ and aVF leads indicates CAD probability. It is indefinite to judge the pathological coronary artery by the fragmented QRS complex of electrocardiogram.
