Abstract
An implantable cardiac stimulation device provides pacing stimulation therapy from within the left ventricle of a heart. The device includes a pulse generator adapted to be coupled to an implantable cardiac stimulation electrode and a power supply that maintains the stimulation electrode at a negative voltage. The electrode may be implanted within the left ventricle by feeding the electrode from the right ventricle through the right ventricular septum and into the left ventricle.
