Catheter cryoablation of ventricular ectopy originating from his region

Andrea Rossi et al. Clin Case Rep. .

Abstract

Careful mapping, early detection of AV conduction damage and cryothermal energy availability are essential in dealing with ablation procedures at the parahisian region.

Keywords: cryoablation; premature ventricular complexes.
