Patent ID: 7010358

Claim:
An implantable cardiac lead for placement in a coronary sinus region of a heart, the lead comprising: a lead body defining a distal end and a proximal end; a plurality of terminals at the proximal end of the lead body; an electrode assembly comprising a defibrillation electrode and first and second pacing electrodes, the first pacing electrode spaced from the defibrillation electrode and positioned proximate to the distal end of the lead body for placement in electrical contact with an apex of a left ventricle of the heart, the second pacing electrode spaced proximally from the defibrillation electrode for placement in electrical contact with a basal region of the left ventricle of the heart; and a plurality of conductors connecting each electrode to a respective one of the terminals at the proximal end of the lead body; wherein the first and second pacing electrodes respectively stimulate the apex and basal region simultaneously.
