Abstract:
1. An implantable device comprising: a first connector, for a first supraventricular electrode that is proportioned for disposition on an intravascular lead within a supraventricular region of the heart; a second connector, for a first ventricular electrode that is proportioned for disposition on the same intravascular lead within a ventricle of the heart; wherein the device permits delivering atrial anti-tachyarrhythmia therapy between two electrodes located on the same intravascular lead, the two electrodes consisting of the first supraventricular and first ventricular electrodes, in response to atrial heart activity indicating a need for atrial anti-tachyarrhythmia therapy; and an atrial sensor, coupled to the device, to sense the atrial heart activity indicating a need for atrial anti-tachyarrhythmia therapy, wherein the atrial sensor includes a second supraventricular electrode for sensing the atrial heart activity indicating a need for atrial anti-tachyarrhythmia therapy, and wherein the atrial sensor includes a third supraventricular electrode for sensing the atrial heart activity indicating a need for atrial anti-tachyarrhythmia therapy.
