ABSTRACT:
A subcutaneous implantable cardiac device system applies defibrillation currents in pathways aligned with the heart's own electrical system to decrease defibrillation thresholds. In one implementation, one or more subcutaneous sensors detect ventricular fibrillation. Positioning of subcutaneous sensors and filtering result in improved sensing with reduced noise. A subcutaneous patch component of the system that is in communication with a subcutaneous pacemaker or cardioverter-defibrillator may perform the sensing and apply the defibrillation. The subcutaneous patch may include one or more electrodes that perform both sensing and defibrillation. Variations of the subcutaneous patch may include battery and capacitor for generating onboard defibrillation current and may also include a microprocessor for advanced programmable operation.
