Unpinning Termination Therapy for VT (US)

Study Overview
=================
Brief Summary
-----------------
This observation study evaluates the safety and performance of UPT therapy in subjects during either an indicated ventricular tachycardia ablation procedure or an ICD implant procedure.

Detailed Description
-----------------
This non-blinded, single-arm open-label, phase 1 pilot, acute research feasibility trial aims to demonstrate that the safety and effectiveness of Unpinning Termination (UPT) electrotherapy observed in the canine can be translated to humans and to demonstrate the safety and performance of UPT electrotherapy in the human population most likely to benefit from this therapy. This study evaluates the safety and performance of UPT therapy in subjects during either an indicated ventricular tachycardia (VT) catheter ablation or an indicated initial implant or device replacement of an implantable cardioverter defibrillator (ICD).
