Objective:To analyze the short-term prognosis of chronic heart failure(CHF)patients with different R/S wave ratios of premature ventricular contractions in inferior leads.Methods Ninety-three CHF patients with premature ventricular contraction in holter examination admitted to the hospital from March 2020 to March 2022 were selected.All patients completed 24h holter moni-toring and were followed up for one year.According to the short-term prognosis,the patients with adverse cardiac events such as acute myocardial infarction and malignant arrhythmia were included in the poor prognosis group(n=37),and the remaining patients without adverse cardiac events were included in the good prognosis group(n=56).The prognosis of ventricular premature beat R/S wave ratio in different inferior leads was compared between the two groups.Results There were no significant differences in age,BMI,smoking,hypertension,diabetes,LVEF,diuretics and digoxin between the two groups(P＞0.05).There were significant differ-ences in gender and NYHA classification between the two groups(P＜0.05).The proportion of patients with R/S ratio ≥1 in the good prognosis group was higher than that in the poor prognosis group,and the proportion of patients with R/S ratio＜1 was lower than that in the poor prognosis group,and the difference was statistically significant(P＜0.05).Logistic regression analysis showed that R/S ratio＜1,gender and NYHA classification were independent risk factors for poor short-term prognosis of CHF patients(P＜0.05).Conclusion The R/S ratio of ventricular premature contraction in different inferior leads is correlated with its prognosis,and R/S ratio＜1 is a predictor of poor prognosis.
