Ablation at sites with electrogram frequency >325 Hz was successful in all patients with premature ventricular contractions.
Does ablation guided by higher electrogram frequency and smaller isochronal activation surface area mapping improve successful ablation in patients with premature ventricular contractions?
Targeting ablation sites with electrogram frequencies > 325 Hz and smaller isochronal activation surface areas may guarantee procedural success for premature ventricular contractions.

Higher EGM frequency and smaller IASA were associated with successful ablation of PVCs. Ablation at sites with EGM frequency > 325 Hz was successful in all patients. The utility of identifying higher frequency EGMs at early activation sites requires further study.
Hoffer-Hawlik et al. (Thu,) reported a other. Ablation at sites with electrogram frequency >325 Hz was successful in all patients with premature ventricular contractions.
