Patent ID: 11534616

Abstract:
A subcutaneous cardiac defibrillation system implantable comprising a housing and a subcutaneous implantable lead comprising a proximal end connected to the housing and a distal free end. The subcutaneous implantable lead comprises at least one defibrillation electrode and at least three detection electrodes. The first detection electrode and the second detection electrode form a first dipole, and the third detection electrode and the first detection electrode, or the third detection electrode and the second detection electrode, or the housing and one of said detection electrodes, form a second dipole. The defibrillation electrode is positioned between the second detection electrode and the third detection electrode, the first dipole is positioned between the housing and the defibrillation electrode, the third electrode is positioned between the free distal end of the lead and the defibrillation electrode, and the length of the first dipole is shorter than the length of the second dipole.
