Ventricular pacing
First Claim
1. A method for treating a condition of a heart of a patient, comprising:
- placing at least one of a first electrode and a second electrode in a right ventricle of the heart for use in presenting energy that is defined relative to a reference electrode;
finding a target location in the right ventricle at or near a bundle of His and securing said at least one of the first and second electrodes at the target location;
generating a pacing signal including first and second signal components having opposite polarity and at least partially overlapping in time and with both of said first and second components having a potential relative to said reference electrode; and
applying the pacing signal to the heart at the target location via the first and second electrodes to elicit a contraction of a left ventricle of the heart.

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 comprising:
-
placing a primary electrode in a right ventricle of a heart, wherein the patient'"'"'s heart, includes a conduction block in a bundle branch; securing the primary electrode to the septum of the heart to treat the condition; and generating a pacing signal of less than about 20 Volts for presentation to the right ventricle by the primary electrode with the pacing signal presenting a voltage on the primary electrode relative to a reference voltage, and wherein the pacing signal causes an activation of the normal electrical conduction in the heart and therein treating the mechanical asynchrony by improving the coordinated contraction of the ventricles and free wall of the left ventricle, wherein the pacing signal includes first and second signal components having opposite polarity and at least partially overlapping in time. - View Dependent Claims (14, 15, 16, 17, 18)
