All data are presented as mean ± SD or in percent. Expense is measured in RMB. PVCs = premature ventricular complexes. LVEF = left ventricular ejection fraction. LVESD = left ventricular end-systolic dimension. LVEDD = left ventricular end-diastolic dimension. BMI = body mass index. CRp = C-Reactive protein. Number of PVCs was determined by Holter before ablation. Significant difference was found in patients suffered complication and patients free from complication for age, hypertension and hospital stays
