Efficacy of a Right-sided Ablation of the Anterior Ganglionated Plexus for Neurally Mediated Syncope

EPS and electro-anatomical mapping of the right atrium and the surrounding veins. A target line (TL) is traced at the posteroseptal side of the junction, between the right atrium and superior vena cava, facing the mid and caudal parts of the right superior pulmonary vein antrum on the right heart cavities on a CT image imported into the CARTO system. This map will be carefully merged with the CT image and the TL will be visible. Sequential ablations will be delivered along theTL until the procedure endpoint is reached. Pharmacological evaluation.
