Abstract
A method and apparatus are disclosed for treating a condition of a patient's heart includes placing a first electrode and a second electrode in a right ventricle of the heart. 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 first component is transmitted to the first electrode. The second component is transmitted to the second electrode. The reference electrode is connected to the reference component which may be an electrical ground. The pacing signal and the placement of the electrodes are selected to alter a contraction of a left ventricle of the heart.
