摘　　要：目的分析急诊心力衰竭(心衰)患者心电图、心脏超声与心功能的相关性。方法将2020年10月至2021年10月于我院收治的100例急诊心衰患者纳入观察组,另将同期常规体检的100例健康志愿者纳入对照组,两组均行心电图及心脏超声检测并比较其结果;参照纽约心脏病协会(NYHA)分级标准对观察组患者进行心功能分级,比较不同心功能分级患者的心电图、心脏超声结果,运用Pearson相关性分析法分析心电图、心脏超声与心功能分级的相关性。结果观察组心率(HR)、QT间期、QTc间期、QTd间期、左室舒张期内径(LVDD)、左室收缩期内径(LVSD)、左心室舒张末期容积(LVEDV)、左心室收缩末期容积(LVESV)、左房内径(LAD)均大于对照组(P<0.05),血流峰值速度比值(E/A)、左心室短轴缩短率(LVFS)均小于对照组(P<0.05)。两组舒张期室间隔厚度(IVST)、左室后壁厚度(LVPWT)、每搏输出量(SV)、心输出量(CO)、心脏指数(CI)相近(P>0.05)。观察组不同心功能分级患者的HR、QT间期、QTc间期、QTd间期、LVDD、LVSD、LVEDV、LAD、LVFS比较存在明显差异(P<0.05)。Pearson相关性分析结果显示,心功能分级与HR、QT间期、QTc间期、QTd间期、LVDD、LVSD、LVEDV、LAD呈显著正相关,与LVFS呈显著负相关。结论急诊心衰患者心电图、心脏超声与心功能分级间存在显著相关性,可为临床评测心功能提供参考依据。Objective To analyze the correlation among electrocardiogram(ECG),cardiac ultrasound and heart function in patients with emergency heart failure(HF).Methods The patients with emergency HF(n=100)were chosen into observation group and synchronous healthy controls with routine body examinations(n=100)were chosen into control group from Hospital of Traditional Chinese Medicine of Huairou District of Beijing from Oct.2020 to Oct.2021.All groups were given examinations of ECG and cardiac ultrasound and the results were compared.According to the classification standard of New York Heart Association(NYHA),the heart function classification was conducted in patients in observation group,and the results of ECG and cardiac ultrasound examinations were compared among patients with different NYHA grades.The correlation among ECG,cardiac ultrasound and heart function classification was analyzed by using Pearson correlation analysis.Results The indexes of heart rate(HR),QT interval,QTc interval,QTd interval,left ventricular diastolic diameter(LVDD),left ventricular systolic diameter(LVSD),left ventricular end-diastolic volume(LVEDV),left ventricular end-systolic volume(LVESV)and left atrial diameter(LAD)were all higher in observation group than those in control group(P<0.05).The peak flow velocity ratio(E/A)and left ventricular fraction shortening(LVFS)were lower in observation group than those in control group(P<0.05).The indexes of interventricular septal thickness(IVST),left ventricular posterior wall thickness(LVPWT),stroke volume(SV),cardiac output(CO)and cardiac index(CI)were similar between 2 groups(P>0.05).The indexes of HR,QT interval,QTc interval,QTd interval,LVDD,LVDS,LVEDV,LAD and LVFS had significant difference in patients with different NYHA grades in observation group(P<0.05).The results of Pearson correlation analysis showed that heart function classification was positively correlated to HR,QT interval,QTc interval,QTd interval,LVDD,LVDS,LVEDV and LAD,and negatively correlated to LVFS.Conclusion ECG and cardiac u
