Ablation of Reentry-Vulnerable-Zones Determined by Left Ventricular Activation from Multiple Directions: A Novel Approach for Ventricular Tachycardia Ablation: A Multicenter Study (PHYSIO-VT).

Background - The optimal method to identify the arrhythmogenic substrate of scar-related VT is unknown. Sites of activation slowing during sinus rhythm (SR) often co-localize with the VT circuit. H...
