Comparison of Radiofrequency Ablation using Anatomical Approach to Activation Approach in Patients with Idiopathic Verapamil-Sensitive Left Ventricular Tachycardia

Background: Different methods have been proposed for the ablation of Idiopathic Left Ventricular Tachycardia (ILVT). These include pace-mapping method and ablation targeting Purkinje Potential or Diastolic Potential during Ventricular Tachycardia (VT). In patients with non-inducible or non-stable VT, these critical potentials might be difficult to map. Radiofrequency ablation (RFA) during sinus rhythm in ILVT has been reported in case series but...
