Initially, 25 398 patients were screened. After excluding patients who met the exclusion criteria, 16 030 patients were enrolled in the study. A propensity score‐matched analysis was used to compare the low burden (PVC daily count <1000) and moderate and high burden (PVC daily count >1000) groups, with a ratio of 4:1. After a median follow‐up time of 973 days, the incidences of new‐onset atrial fibrillation were 2.79% and 4.96% in the low‐burden and moderate‐to‐high‐burden groups, respectively (P<0.001). AF indicates atrial fibrillation; and PVC, premature ventricular complex.
