摘　　要：目的探讨碎裂QRS波(fQRS)在急性冠脉综合征的诊断价值。方法选取159例急性冠脉综合征患者,根据是否存在fQRS进行分组,分析fQRS对不稳定型心绞痛,非ST段抬高型及ST段抬高型心肌梗死的诊断价值。结果 fQRS波诊断ST段抬高型和非ST段抬高型心肌梗死的敏感度分别为47.5%和35.4%,仅3.75%不稳定型心绞痛患者出现fQRS。结论 fQRS可作为急性心肌梗死的诊断指标。Objective To explore the value of fragmented QRS （fQRS） in the diagnosis of acute myocardial infarction. Methods We enrolled 159 cases with acute coronary syndrome, and divided them into 2 groups according to fQRS wave, the fQRS group and the non-fQRS group. Then we analyzed the value of fQRS in the diagnosis of unstable angina pectoris and non-ST segment elevation AMI （NSTEMI） and ST segment elevation AM! （STEMI）. Results The sensitivity of fQRS on the diagnosis of NSTEMI and STEMI and unstable angina pectoris are 47.5%, 35.4% and 3.75%. Conclusion fQRS is useful in the diagnosis of acute myocardial infarction.
