ABSTRACT:
Heart tissue near the surface of the heart is characterized to identify a potential site to ablate to treat reentrant ventricular tachycardia. Signals from the surface of the heart are recorded during an episode of ventricular tachycardia to determine whether a reentrant pathway lies near the surface of the heart. Entrainment pacing is employed to identify a potential ablation site near the slow conduction zone of the reentrant pathway. Heart tissue is ablated by creating a lesion with a large surface area and a shallow depth to destroy the slow conduction zone.
