摘　　要：目的分析不同下壁导联室性早搏R/S波比值的慢性心力衰竭患者近期预后。方法选取2019年3月至2021年10月在本院就诊的慢性心力衰竭患者92例,下壁导联室性早搏R/S波比值分组,即R/S≥1组、R/S<1组。统计主要终点事件和次要终点事件。结果共29例发生NSVT,其中R/S≥1组7例(24.14%),R/S<1组22例(75.86%),R/S<1组NSVT发生率75.86%高于R/S≥1组,差异具有统计学意义(x^(2)=6.446,P=0.011)。R/S比值是影响患者主要终点事件因素(OR:0.305,95%CI:0.125~0.771,P=0.013)。R/S≥1组首次心衰至再住院间隔时间高于R/S<1组,心衰再住院率低于R/S<1组,P<0.05。R/S比值是影响患者次要终点事件因素(OR:2.905,95%CI:1.435~5.861,P=0.004)。结论下壁导联室性早搏的R/S波比值<1的慢性心力衰竭患者预后较差,其主要终点事件和次要终点事件发生率更高,再住院率也更高。因此,R/S波比值可能是慢性心力衰竭患者近期预后的独立危险因素。Objective:To analyze the short-term prognosis of patients with chronic heart failure with different R/S wave ratios of ventricular premature beats with inferior wall leads.Methods:A total of 92 patients with chronic heart failure admitted to our hospital from March 2019 to October 2021 were selected.The R/S wave ratio of the lower wall lead ventricular premature beat was divided into groups,i.e.,R/S≥1 group and R/S<1 group.Primary and secondary endpoints were counted.Results:A total of 29 cases developed NSVT,including 7 cases(24.14%)in R/S≥1 group and 22 cases(75.86%)in R/S<1 group.The incidence of NSVT in R/S<1 group was higher at 75.86%than that in R/S≥1 group,and the difference was statistically significant(χ^(2)=6.446,P=0.011).R/S ratio was the primary end-point event factor for patients(OR:0.305,95%CI:0.125~0.771,P=0.013).The interval between first heart failure and readmission in R/S≥1 group was higher than that in R/S<1 group,and the readmission rate of heart failure in R/S<1 group was lower than that in R/S<1 group,P<0.05.R/S ratio was the event factor affecting the secondary end point in patients(OR:2.905,95%CI:1.435~5.861,P=0.004).Conclusion:Chronic heart failure patients with an R/S wave ratio<1 for lower wall lead ventricular premature beat had poorer outcomes,higher rates of primary and secondary endpoint events,and higher rates of readmission.Therefore,R/S wave ratio may be an independent risk factor for near-term prognosis in patients with chronic heart failure.
