  • Title: Catheter ablation of premature ventricular contractions originating from the His bundle region.
    Author: Ashikaga K, Tsuchiya T, Nakashima A, Hayashida K.
    Journal: Europace; 2007 Sep; 9(9):781-4. PubMed ID: 17507357.
    Abstract:
    We describe a 35-year-old man with idiopathic frequent premature ventricular contractions (PVCs) originating from the His-bundle region, where a low frequency ventricular potential was recorded in the bipolar recording and QR pattern in the unipolar recording. Electro-anatomical mapping revealed a confined low voltage zone (<1.2 mV) in the His-bundle region, and the activation spread out radially to the entire right ventricle. The PVCs were successfully abolished without any atrioventricular block by a step-wise incremental radiofrequency energy application to the His-bundle region. The patient has remained free from PVCs or any symptoms without medication during a 23 month follow-up period.
