摘要
目的比较心力衰竭患者心电图QRS波不同时限及振幅时心功能的情况。方法选择我院2018年4月至2021年4月住院治疗的心力衰竭患者97例作为观察组(A组),另选择同期48例健康体检者作为对照组(B组),收集并整理其完整心电图及临床资料。分析心衰不同QRS波振幅特点,对比两组ΣQRS振幅、R_(Ⅰ)+S_(Ⅲ)振幅、R_(V1)+S_(V5)振幅;比较QRS<120ms、QRS≥120ms患者的ΣQRS振幅、射血分数(LVEF)、左房内径(LAD)、左室舒张末期内径(LVEDd)指标。结果观察组ΣQRS振幅、R_(Ⅰ)+S_(Ⅲ)振幅、R_(V1)+S_(V5)振幅低于对照组(P<0.05)。QRS<120ms组的ΣQRS振幅高出QRS≥120ms组(P<0.05)。两组LAD比较无差异(P>0.05),但QRS<120ms组LVEF高出QRS≥120ms组,LVEDd低于QRS≥120ms组(P<0.05)。结论心力衰竭患者QRS波振幅较低,QRS波时限≥120m患者的心功能较差,QRS波振幅和时限对于评估患者的心功能有一定的作用。
Objective To compare the cardiac function of patients with heart failure at different QRS durations and amplitudes.Methods A total of 97 patients with heart failure who were hospitalized in our hospital from April 2018 to April 2021 were selected as the observation group(group A),and 48 healthy subjects during the same period were selected as the control group(group B).Electrocardiogram and clinical data were collected.The characteristics of different QRS complex amplitudes in heart failure were analyzed,and the ΣQRS amplitude,R_(Ⅰ)+S_(Ⅲ)amplitude,and R_(V1)+S_(V5) amplitude were compared between the two groups;the ΣQRS amplitude,ejection fraction(LVEF),left atrial diameter in patients with QRS<120ms and QRS≥120ms(LAD)and left ventricular end-diastolic diameter(LVEDd).Results The amplitudes of ΣQRS,R_(Ⅰ)+S_(Ⅲ)and R_(V1)+S_(V5) in the observation group were lower than those in the control group(P<0.05).The amplitude ofΣQRS in the QRS<120ms group was higher than that in the QRS≥120ms group(P<0.05).There was no difference in LAD between the two groups(P>0.05),but the LVEF in the QRS<120ms group was higher than that in the QRS≥120ms group,and the LVEDd was lower than that in the QRS≥120ms group(P<0.05).Conclusions The QRS wave amplitude in patients with heart failure is low,and the cardiac function of patients with QRS wave duration≥120ms is poor.The QRS wave amplitude and duration have a certain role in evaluating the cardiac function of patients.
