The Lead Episode 92: A Discussion of Substrate Mapping for Ventricular Tachycardia Ablation Through High-Density Whole-Chamber Double Extra Stimuli

William Sauer, MD, FHRS, CCDS, Brigham and Women’s Hospital is joined by Wendy Tzou, MD, FHRS, University of Colorado Anschutz Medical Campus, and Arif Elvan, MD, PhD, Klinikum Braunschweig, to discuss a partial delineation of targets for ablation of ventricular tachycardia (VT) during a stable rhythm is likely responsible for a suboptimal success rate. The abnormal low-voltage near-field functional components may be hidden within the high-amplitude far-field signal.
