Patent ID: 8050759

Claim:
An implantable cardioverter defibrillator (ICD) system comprising: a cardiac rhythm sensor for sensing cardiac activity and transmitting wirelessly a cardiac rhythm signal, wherein the cardiac rhythm sensor is configured to produce the cardiac rhythm signal only when a bradycardia or tachycardia condition exists; a subcutaneous implantable lead carrying a defibrillation electrode; and a subcutaneous implantable cardioverter defibrillator (SubQ ICD) for receiving the cardiac rhythm signal transmitted by the cardiac rhythm sensor and detecting tachycardia or bradycardia based on the cardiac rhythm signal, wherein the SubQ ICD is connected to the lead for providing electrical pulses to the defibrillation electrode upon the SubQ ICD detection of tachycardia or bradycardia based on the cardiac rhythm signal transmitted by the cardiac rhythm sensor to the SubQ ICD, wherein the SubQ ICD includes at least one electrode located on a housing of the SubQ ICD and configured to receive the cardiac rhythm signal and apply pacing pulses.
