Catheter Ablation of Ventricular Arrhythmia in Nonischemic Cardiomyopathy

Abstract

Unipolar low-voltage distribution in nonischemic cardiomyopathy allows categorization of scar pattern as inferolateral, often requiring epicardial ablation mainly based on late potentials, and anteroseptal, which frequently involves an intramural septal substrate, leading to a higher VT recurrence.
