摘　　要：目的分析心电图碎裂QRS波(fQRS)联合病理性Q波对急性心肌梗死(AMI)的诊断价值。方法将我院2020年1月至2021年12月收治的100例冠心病患者纳入本次研究,以心电图诊断结果差异将其分为AMI组(n=52)和非AMI组(n=48)。所有患者均接受心电图检查,根据心电图ST段是否抬高将52例AMI患者分为ST段抬高组与ST段未抬高组,比较两组的fQRS波、病理性Q波发生情况;以病理学检查结果为金标准,比较fQRS波、病理性Q波单独及联合检测对AMI的诊断效能,包括灵敏度、特异度、准确度、阳性预测值、阴性预测值;根据fQRS波是否出现将52例AMI患者分为fQRS波组与非fQRS波组,随访追踪两组患者1年内心血管不良事件发生率与再次住院率。结果ST段抬高组的fQRS波发生率低于ST段未抬高组,病理性Q波发生率高于ST段未抬高组(P<0.05)。fQRS波、病理性Q波联合诊断AMI的灵敏度、准确度、阴性预测值高于单独诊断(P<0.05)。fQRS波组的各项心血管不良事件发生率及再次住院率高于非fQRS波组(P<0.05)。结论心电图fQRS波联合病理性Q波能有效提高AMI诊断效能,特别是fQRS波能够评估患者预后,具有较高应用价值。Objective To analyze the diagnostic value of fragmented QRS complex(fQRS)combined with pathological Q wave of electrocardiogram in acute myocardial infarction(AMI).Methods A total of 100 patients with coronary heart disease admitted in our hospital from January 2020 to December 2021 were included in this study.According to the difference of electrocardiogram diagnosis results,the patients were divided into AMI group(n=52)and non-AMI group(n=48).All patients underwent electrocardiogram examination,according to whether the ST segment of electrocardiogram was elevated,52 patients with AMI were divided into ST segment elevation group and ST segment non-elevation group,and the occurrence of fQRS and pathological Q wave was compared between the two groups;with the results of pathological examination as the gold standard,the diagnostic efficacy of fQRS,pathological Q wave alone and combined detection for AMI were compared,including sensitivity,specificity,accuracy,positive predictive value and negative predictive value;according to the presence or absence of fQRS,52 patients with AMI were divided into fQRS group and non-fQRS group,and the incidence of cardiovascular adverse events and rehospitalization rate within 1 year of the two groups were followed up.Results The incidence of fQRS in the ST segment elevation group was lower than that in the ST segment non-elevation group,and the incidence of pathological Q wave was higher than that in the ST segment non-elevation group(P<0.05).The sensitivity,accuracy and negative predictive value of fQRS combined with pathological Q wave in the diagnosis of AMI were higher than those of single diagnosis(P<0.05).The incidences of cardiovascular adverse events and rehospitalization rate in the fQRS group were higher than those in the non-fQRS group(P<0.05).Conclusion fQRS combined with pathological Q wave of electrocardiogram can effectively improve the diagnostic efficacy of AMI,especially fQRS,which can evaluate the prognosis of patients and has high application value.
