The impact of catheter ablation on the burden of premature ventricular contractions. A postprocedural reduction of the burden of premature ventricular contractions was observed in patients with and without structural heart disease. The burden at follow-up was higher in patients with structural heart disease. The bars show mean with standard deviation. *p < 0.05 was considered statistically significant.
