摘　　要：目的:观察心电图碎裂QRS波联合病理性Q波在急性心肌梗死(AMI)诊断中的效能。方法:选取2020年1月至2022年12月该院收治的200例冠心病患者进行横断面研究,均行心电图和冠状动脉造影检查,以冠状动脉造影检查结果为金标准。按照是否为AMI将其分为AMI组(n=100)和非AMI组(n=100),比较两组心电图检查碎裂QRS波、病理性Q波、碎裂QRS波+病理性Q波检出率,分析心电图检查碎裂QRS波、病理性Q波单项及联合检查诊断AMI的效能,并比较不同类型AMI碎裂QRS波检出率。结果:AMI组碎裂QRS波、病理性Q波、碎裂QRS波+病理性Q波检出率均高于非AMI组,差异有统计学意义(P<0.05);碎裂QRS波、病理性Q波联合诊断AMI的灵敏度高于二者单项诊断,差异有统计学意义(P<0.05);ST段抬高型AMI碎裂QRS波检出率高于非ST段抬高型,差异有统计学意义(P<0.05)。结论:心电图碎裂QRS波联合病理性Q波诊断AMI的效能高于二者单项诊断。Objective:To observe efficiency of fragmented QRS wave combined with pathological Q wave in diagnosis of acute myocardial infarction(AMI).Methods:A cross-sectional study was conducted on patients with coronary heart disease admitted to this hospital from January 2020 to December 2022.Electrocardiogram and Coronary angiography were performed.They were divided into AMI group(n=100)and non-AMI group(n=100)according to whether AMI occurred.Using the results of coronary angiography as the gold standard,the detection rates of fragmented QRS wave,pathological Q wave and fragmented QRS wave+pathological Q wave were compared between the two groups.The efficiencies of single and combined examination of fragmented QRS wave and pathological Q wave in the diagnosis of AMI were analyzed.The detection rate of fragmented QRS wave in different types of AMI was compared.Results:The detection rates of fragmented QRS wave,pathological Q wave and fragmented QRS wave+pathological Q wave in AMI group were higher than those in non-AMI group,and the differences were statistically significant(P<0.05).The sensitivity of combined examination of fragmented QRS wave and pathological Q wave in the diagnosis of AMI was higher than that of single examination,and the difference was statistically significant(P<0.05).The detection rate of fragmented QRS wave in ST-segment elevation AMI was higher than that in non-ST-segment elevation AMI,and the differences were statistically significant(P<0.05).Conclusions:The efficiency of fragmented QRS wave combined with pathological Q wave in the diagnosis of AMI is higher than that of single diagnosis.
