摘　　要：目的:探究心电图应用于急性心肌梗死(AMI)患者诊断中的效果。方法:2018年7月-2019年7月收治冠心病患者194例,其中AMI患者103例,非AMI患者91例。所有患者均行心电图检查,对照病理检查结果。比较碎裂QRS波、病理性Q波、碎裂QRS波联合病理性Q波诊断AMI的特异度和敏感度,并分析其临床应用价值。结果:通过病理学检查确认AMI患者103例。碎裂QRS波、病理性Q波、碎裂QRS波联合病理性Q波诊断的阳性率、阴性率比较,差异有统计学意义(P<0.05)。碎裂QRS波、病理性Q波对心肌梗死的诊断敏感性、特异性比较,差异无统计学意义(P>0.05);碎裂QRS波联合病理性Q波指标对AMI的诊断敏感度、准确度均明显高于单一指标检查,差异有统计学意义(P<0.05);但碎裂QRS波、病理性Q波、碎裂QRS波联合病理性Q波三者特异性相比,差异无统计学意义(P>0.05)。结论:对AMI患者应用心电图进行诊断,有助于提升AMI的诊断准确率和有效率。Objective:To explore the effect of electrocardiogram in the diagnosis of acute myocardial infarction(AMI).Methods:From July 2018 to July 2019,194 patients with coronary heart disease(CHD)were selected,including 103 patients with AMI and 91 patients with non-acute myocardial infarction.All patients received electrocardiogram examination and compared with pathological examination results.To compare the specificity and sensitivity of cataclastic QRS,pathological Q wave,cataclastic QRS combined with pathological Q wave in the diagnosis of acute myocardial infarction,and to compare their clinical application value respectively.Results:103 cases of AMI were confirmed by pathological examination.Comparison of positive and negative rates of three ECG indicators,with the differences were statistically significant(P<0.05).Comparison of sensitivity and specificity of cataclastic QRS wave and pathological Q wave in the diagnosis of myocardial infarction,with the difference was not statistically significant(P>0.05).The sensitivity and accuracy of the combination of the two indexes in the diagnosis of AMI were significantly higher than the single indicator group,with the differences were statistically significant(P<0.05).But compared to the specificity of the three,with the difference was not statistically significant(P>0.05).Conclusion:Applying electrocardiogram to the diagnosis of acute myocardial infarction is helpful to improve the accuracy and efficiency of the diagnosis.
