  • Method and apparatus for anti-tachycardia pacing and defibrillation
    Patent number: 8131360
    Abstract: An implantable cardioverter/defibrillator (ICD) includes an Anti-Tachycardia Pacing Before Charge (ATP-BC) mode according to which one or more high-voltage capacitors for storing defibrillation energy are charged in preparation of delivering a defibrillation shock only if a ventricular tachycardia (VT) sustains after an ATP delivery. Fast ATP delivery and effect verification methods are applied to avoid significant delay in delivering the defibrillation shock when found necessary to terminate the VT. A switch is provided such that a user decides whether to activate the ATP-BC mode or to deliver the defibrillation shock without delivering the ATP.
    Type: Grant
    Filed: January 17, 2011
    Date of Patent: March 6, 2012
    Assignee: Cardiac Pacemakers, Inc.
    Inventors: David L. Perschbacher, Karin K. Roof, Rebecca Bloomfield
