Popis: Background: As with the use of circular catheters for pulmonary vein antral ablation, it may be favorable to use multipolar catheters for substrate mapping of the left ventricle (LV). The purpose of this study was to investigate the clinical feasibility of using multielectrode mapping combined with an impedance-based electroanatomic mapping system for scar-mediated ventricular tachycardia (VT). Methods: By using the multielectrode catheter in conjunction with the Velocity system, we obtained both geometric and electrogram data simultaneously, through transseptal and transsubxiphoid approaches. Higher-density mapping was performed in areas of dense scar (
