摘　　要：目的探究急性前壁心肌梗死患者心电图碎裂QRS波与左室收缩功能的相关性。方法前瞻性选取2018年1月至2020年8月蚌埠市第三人民医院收治的100例急性前壁心肌梗死患者作为研究对象,根据心电图f QRS波形态将患者分为碎裂QRS波(A组,n=35)、病理性Q波(B组,n=40)与碎裂QRS波联合病理性Q波(C组,n=25)。检测3组左室收缩功能指标,分析碎裂QRS波与左室收缩功能相关性,随访3组患者不良事件发生率。结果B组左室射血分数(LVEF)为(54.69±6.51)%,高于A组[(45.32±6.43)%]与C组[(48.59±6.45)%],左室舒张末期内径(LVEDD)为(45.63±6.69)mm,低于A组[(52.54±7.78)mm]与C组[(51.39±7.42)mm],差异均有统计学意义(P<0.05)。相关性分析结果显示,f QRS波与LVEF呈负相关(r=-0.535,P<0.05),与LVEDD呈明显正相关(r=0.783,P<0.05);随访3组不良事件发生率A组、C组分别为14.29%、24.00%,高于B组(0),差异有统计学意义(P<0.05)。结论急性前壁心肌梗死患者心电图f QRS波与左室收缩功能密切相关,可通过检测f QRS波评估患者危险分级及预后,为临床诊断及治疗提供帮助。Objective To explore the correlation between cataclastic QRS wave and left ventricular systolic function in patients with acute anterior wall myocardial infarction.Methods A total of 100 patients with acute anterior wall myocardial infarction admitted to the Third People's Hospital of Bengbu City from January 2018 to August 2020 were prospectively selected as the research subjects.According to the ECG FQRS morphology,the patients were divided into fragmentation QRS(group A),pathological Q wave(group B)and fragmentation QRS combined with pathological Q wave(group C).The indicators of left ventricular systolic function in the three groups were detected,the correlation between cataclastic QRS wave and left ventricular systolic function was analyzed,and the incidence of adverse events in the three groups was followed up.Results The left ventricular ejection fraction(LVEF)in group B was(54.69±6.51)%,which was higher than that in group A[(45.32±6.43)%]and group C[(48.59±6.45)%],and the left ventricular end diastolic diameter(LVEDd)was(45.63±6.69)mm,which was lower than that in group A[(52.54±7.78)mm]and group C[(51.39±7.42)mm],the differences were statistically significant(P<0.05);Correlation analysis results showed that FQRS was negatively correlated with LVEF(r=-0.535,P<0.05),and significantly positively correlated with LVEDD(r=0.783,P<0.05).The incidence of adverse events in group A and C was 14.29%,24.00%,which was higher than that in group B(0),and the difference was statistically significant(P<0.05).Conclusion FQRS is closely related to left ventricular systolic function in patients with acute anterior wall myocardial infarction,which can be used to evaluate the risk grade and prognosis of patients,and provide help for clinical diagnosis and treatment.
