　　[摘要]目的 探討高敏肌钙蛋白T（hs-TnT）联合心电图碎裂QRS波对急性心肌梗死（AMI）的早期诊断价值。方法 选择我院2017年10月～2018年10月心血管内科收治的102例AMI患者作为AMI组，同期在院健康体检者78例为对照组，比较两组血清hs-TnT水平及心电图碎裂QRS波发生率;比较AMI组中69例ST段抬高型心肌梗死（STEMI）患者和33例非ST段抬高型心肌梗死（NSTEMI）患者血清hs-TnT水平及心电图碎裂QRS波发生率，比较hs-TnT、心电图碎裂QRS波及两者联合监测对AMI的诊断效能。结果 AMI组血清hs-TnT水平高于对照组，差异有统计学意义（P<）;AMI组中STEMI组血清hs-TnT水平高于NSTEMI组，差异有统计学差异（P<）;AMI组碎裂QRS波发生率高于对照组，差异有统计学意义（P<）;AMI组中STEMI组碎裂QRS波发生率高于NSTEMI组，差异有统计学差异（P<）;hs-TnT联合心电图碎裂QRS波的AMI诊断效能优于单独监测hs-TnT、心电图碎裂QRS波的AMI诊断效能，差异有统计学差异（P<）。结论 对于早期诊断AMI，hs-TnT、心电图碎裂QRS波联合检测较单独检测有更高的敏感度、准确性，能够为临床诊治AMI提供有价值的参考信息。

　　[Abstract] Objective To investigate the early diagnostic value of high-sensitive troponin T （hs-TnT） combined with fragmented QRS complex in acute myocardial infarction （AMI）. Methods A total of 102 cases of AMI （AMI group） admitted to our department of cardiology and 78 cases of healthy examinees （control group） were selected from October 2017 to October 2018 in our hospital. The serum hs-TnT level and the incidence of fragmented QRS complex were compared between the two groups， as well as between ST-segment elevation myocardial infarction patients（STEMI group， n=69） and non-ST-segment elevation myocardial infarction patients（NSTEMI group， n=33）. Then the diagnostic efficacy of single detection and combined detection of serum hs-TnT level and fragmented QRS complex in the diagnosis of the AMI were compared. Results The level of serum hs-TnT in AMI group was higher than that in control group（P<）. The level of serum hs-TnT in STEMI group was higher than that in NSTEMI group in AMI group （P<）. The incidence of fragmented QRS complex in the AMI group was higher than that of the control
