    Supplementary Material for: Risk factors and heart rate variability associated with left ventricular enlargement in patients with frequent premature ventricular contractions by Yang Z. (4129039)

    Published 2022
    “…Multivariate analysis showed that female gender (odds ratio (OR)=2.753, p<0.001), increased NT-proBNP (OR=1.011, p=0.022), increased LVEF (OR=0.292, p<0.001), increased 24-hour PVCs burden (OR=1.594, p<0.001), increased standard deviation of all NN intervals (SDNN) (OR=1.100, p=0.003), increased the proportion of consecutive NN intervals that differ by more than 50ms (PNN50) (OR=0.844, p=0.026) were predictors for LV enlargement in patients with frequent PVCs. 84.4% (54/64) of patients with LV enlargement at baseline had normalized their LV structure after ablation. …”
