急性心肌梗死患者心电图特征分析

Electrocardiogram feature analysis in acute myocardial infarction patients

目的研究急性心肌梗死患者的心电图特征,并进行分析,为临床诊断提供有力的依据。方法 85例急性心肌梗死患者作为研究对象,均进行心电图检查,采用回顾性分析的研究方式归纳总结患者临床资料,重点探究心电图的早期特异性表现。结果 85例患者中典型心肌梗死占44.71%,不典型心肌梗死占54.12%,正常心电图占1.18%;ST段抬高患者室性心律失常发生率(36.84%)、死亡率(15.79%)与非ST段抬高患者室性心律失常发生率(8.70%)、死亡率(2.17%)相比较高,差异均具有统计学意义(P<0.05)。结论急性心肌梗死患者心电图表现分为典型与不典型两种,临床检查中行18导联心电图检查(常规12导联心电图及右胸、正后壁导联),以实现早期鉴别诊断,辅助治疗,促进病情预后。

Objective To research electrocardiogram feature analysis in acute myocardial infarction patients for analysis, and to provide powerful basis for clinical diagnosis. Methods A total of 85 patients with acute myocardial infarction as study subjects received electrocardiogram examination. Their clinical data were taken into retrospective analysis for key research of early specific manifestation of electrocardiogram. Results In the 85 patients, typical myocardial infarction accounted for 44.71%, atypical myocardial infarction accounted for 54.12%, and normal electrocardiogram accounted for 1.18%. Patients with ST-segment elevation had higher incidence of ventricular arrhythmias（36.84%） and mortality rate（15.79%） than incidence of ventricular arrhythmias（8.70%） and mortality rate（2.17%） in patients with non-ST-segment elevation. Their differences all had statistical significance（P〈0.05）. Conclusion Electrocardiogram shows typical myocardial infarction and atypical myocardial infarction in acute myocardial infarction patients. Implement of 18-lead electrocardiogram（conventional 12-lead electrocardiogram, right thorax and positive posterior wall lead） in clinical examination can provide early identification, diagnosis, adjuvant therapy, and accelerated prognosis.
