摘　　要：目的:探讨心电图QRS波在射血分数保留型心力衰竭合并房颤诊断中的价值。方法:选取2024年2月至6月安徽省肿瘤医院收治的射血分数保留型心力衰竭合并房颤患者250例及射血分数保留型心力衰竭未合并房颤患者100例。设立两个组进行研究,观察组为射血分数保留型心力衰竭合并房颤患者,对照组为射血分数保留型心力衰竭未合并房颤患者,比较两组的QRS波时限、左室射血分数(LVEF)、左室舒张末期内径(LVEDd)、心功能分级[依据纽约心脏病学会(NYHA)心功能分级标准]与束支传导阻滞发生情况。结果:观察组的QRS波时限及LVEDd高于对照组,LVEF低于对照组,且观察组心功能NYHA分级中的Ⅳ级患者占比以及束支传导阻滞患者占比高于对照组(P<0.05)。结论:射血分数保留型心力衰竭合并房颤患者与未合并房颤患者的心电图QRS波时限、LVEF、LVEDd、心功能分级、束支传导阻滞发生情况存在差异,心电图QRS波检测可用于鉴别诊断射血分数保留型心力衰竭是否并发房颤,辅助临床医生精确评估患者的病情,为临床医生制订合理的治疗方案提供依据。Objective:To investigate the value of electrocardiogram QRS wave in the diagnosis of heart failure with preserved ejection fraction(HFpEF)combined with atrial fibrillation(AF).Methods:250 HFpEF patients with AF and 100 HFpEF patients without AF admitted to Anhui Cancer Hospital from February to June 2024 were selected and divided into an observation group(HFpEF patients with AF)and a control group(HFpEF patients without AF).The QRS wave duration,left ventricular ejection fractions(LVEF),left ventricular end-diastolic diameter(LVEDd),cardiac function grading(according to NYHA cardiac function grading criteria),and incidence of bundle branch block were compared between two groups.Results:The results showed that the QRS wave duration and LVEDd of the observation group were higher than those of the control group,and the LVEF was lower than that of the control group.In addition,the proportion of patients with NYHA grade IV and bundle branch block in the observation group was higher than that of the control group(P<0.05).Conclusion:There are differences in QRS wave duration,LVEF,LVEDd,cardiac function grading,and incidence of bundle branch block between HFpEF patients with AF and HFpEF patients without AF.Electrocardiogram QRS wave detection can be used to differentiate and diagnose whether HFpEF patients are complicated with AF,assist clinical dctors in accurately assessing the patients'condition,and provide a basis for clinical doctors to develop reasonable treatment plans.
