PVC, premature ventricular contraction; OR, odds ratio; CI, confidence interval; LVEF, left ventricular ejection fraction
Figure legends:
Figure 1. The incidence of adverse events in pregnant women with or without PVC. The incidence of adverse events is higher in PVC cases (11.65%) than normal controls without PVC (2.93%). * indicates p<0.05
Figure 2. Incidence of adverse fetal events in low PVC burden (A), medium PVC burden (B) and high PVC burden group (C). A: low PVC burden <the 33rd percentile (<1.69%), B: medium PVC burden, the 33rd percentile - the 67th percentile (1.69%-4.77%), C: high PVC burden >the 67th percentile (>4.77%), * indicates p<0.05
