Ventricular pacing
First Claim
1. An implantable medical device comprising:
- a signal generator configured to;
provide a first electrostimulation energy to a first electrode disposed in a right ventricle of a heart, the first electrostimulation energy having a first potential relative to a reference potential at a first reference electrode; and
provide a second electrostimulation energy to a second electrode disposed in the right ventricle of the heart, the second electrostimulation energy having a second potential relative to the reference potential at the reference electrode;
wherein the first and second electrostimulation energies comprise at least partially overlapping, opposite polarity electrostimulation energies with respect to the reference potential; and
wherein one of the first and second electrodes is configured to be secured to a target location near a bundle of His.

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.

13. A method for providing a therapy to treat a bundle branch block of a heart, the method comprising:
-
generating a pacing signal that includes first and second signal components having opposite polarity and at least partially overlapping in time, wherein the first and second signal components have a potential relative to at least one of multiple reference electrodes placed subcutaneously in or near the heart; applying the pacing signal to the heart using first and second electrodes in or near a right ventricle of the heart and at least one of the multiple refrence electrodes; and identifying a patient physiological response to the applied pacing signal; wherein identifying the patient physiological response includes identifying a ventricular contraction of the heart in the presence of a bundle branch block. - View Dependent Claims (14, 15, 16, 17, 18, 19)
