摘　　要：目的 分析急性心肌梗死患者的右胸及后壁心电图变化。方法 回顾性分析我院在2022年1月至2023年12月收治的78例急性心肌梗死患者(梗死组)及20名常规体检者(健康组)进行研究,所有患者均行心电图检查,采用多因素Logistic回归方法分析独立影响因素。结果 梗死组吸烟高于健康组(P<0.05),且心率、平均动脉压指标低于健康组(P<0.05);2组年龄、性别、体质指数(BMI)、是否饮酒、合并症、脑血管病史、扩张型心肌病差异无统计学意义(P>0.05);梗死组QV7>0.03s、QV8>0.04s、V7Q波与R波的比值(Q/R)>1/3、V8Q/R>1/2、右心室(RV)2=0.04s、ST段弓背或凹面向上或水平下移≥0.05mV、TV_(1)>0.4mV比例高于健康组(P<0.05);2组QV9>0.04s、V9Q/R>1、ST段抬高≥0.1 mV、RV1=0.04s、V1R/S>1、V2R/S>1比例差异无统计学意义(P>0.05);多因素Logistic回归分析结果:吸烟、QV7>0.03 s、QV8>0.04s、V7Q/R>1/3、V8Q/R>1/2、RV_(2)=0.04s、ST段弓背或凹面向上或水平下移≥0.05mV是急性心肌梗死发生的独立影响因素(P<0.05)。结论 急性心肌梗死患者在右胸及后壁心电图上的特征变化包括Q波增宽、QRS波形态异常、ST段异常和T波异常等,这些变化可作为急性心肌梗死的诊断和评估指标。进一步研究这些心电图特征与患者预后之间的关系,有助于提高对急性心肌梗死患者的诊断准确性和治疗效果。Objective To analyze the changes in right chest and posterior wall electrocardiogram in patients with acute myocardial infarction.Methods A retrospective analysis was conducted on 78 patients with acute myocardial infarction(infarction group)and 20 patients undergoing routine physical examination(healthy group)admitted to our hospital from January 2022 to December 2023.All patients underwent electrocardiogram examination,and independent influencing factors were analyzed using the multivariate logistic regression method.Results Smoking in the infarction group was higher than that in the healthy group(P<0.05),heart rate and mean arterial pressure indicators were lower than those in the healthy group(P<0.05).There was no statistically significant difference in age,gender,body mass index(BMI),alcohol consumption,comorbidities,history of cerebrovascular disease,and dilated cardiomyopathy between the two groups(P>0.05).The proportion of QV7>0.03 s,QV8>0.04 s,V7Q/R>1/3,V8Q/R>1/2,RV2=0.04 s,ST segment arch or concave surface moving up or down≥0.05 mV,and TV1>0.4mV in the infarcted group was higher than that in the healthy group(P<0.05).There was no statistically significant difference in the proportions of QV9>0.04 s,V9Q/R>1,ST-segment elevation≥0.1 mV,RV1=0.04 s,V1R/S>1,and V2R/S>1 between the two groups(P>0.05).Multivariate Logistic regression analysis results showed that smoking,QV7>0.03 s,QV8>0.04 s,V7Q/R>1/3,V8Q/R>1/2,RV2=0.04 s,ST segment arch or concave surface upward or horizontal downward displacement≥0.05 mV were all independent influencing factors for the occurrence of acute myocardial infarction(P<0.05).Conclusion The characteristic changes on the right chest and posterior wall electrocardiogram of patients with acute myocardial infarction include Q-wave broadening,abnormal QRS wave morphology,ST segment abnormalities,and T-wave abnormalities,which can serve as diagnostic and evaluation indicators for acute myocardial infarction.Further research on the relationship between these electrocardiogram featur
