Classification: CPC A | IPC A

Claim 14:
15. An implantable cardioverter-defibrillator (ICD) system comprising:
an ICD configured to be implanted subcutaneously in a patient;
a first lead having a proximal portion coupled to the ICD and a distal portion having one or more electrodes, wherein the ICD is configured to deliver electrical stimulation therapy to a heart of the patient via the one or more electrodes of the first lead; and
a second lead comprising a first elongated body that includes a proximal portion coupled to the ICD and a distal portion having one or more electrodes, the distal portion of the second lead having a cylindrical shape along a length of the distal portion to be implanted in a substernal space at least partially along a posterior side of a sternum within an anterior mediastinum of the patient such that the at least one electrode is physically isolated from a pericardium of the patient, the ICD being configured to deliver pacing pulses to a ventricle of the heart of the patient via at least a first electrode of the one or more electrodes of the second lead and deliver pacing pulses to an atrium of the heart of the patient via at least a second electrode of the one or more electrodes of the second lead, the first electrode being different than the second electrode,
wherein the ICD is configured to:
obtain electrical signals of the heart of the patient sensed from the substernal space of the patient using the one or more electrodes of the second lead,
detect a tachycardia using the sensed electrical signals, and
deliver electrical stimulation therapy to the patient using the one or more electrodes of the first lead.
