Abstract
A method and apparatus are disclosed for treating a condition of a patient's heart includes placing a first electrode and/or a second electrode in a right ventricle of the heart. In one example, a reference electrode is placed within the patient and internal or external to the heart. A pacing signal is generated including a first signal component, a second signal component and a reference component with the first and second signal components having opposite polarity and with both of the first and second components having a potential relative to the reference component. The pacing signal and the placement of the electrodes are selected to alter a contraction of a left ventricle of the heart.
