Patent ID: 8825155

Claim:
An apparatus, comprising: an implantable pacing profile generator configured to generate a specified pacing electrostimulation profile for delivery to a heart via electrodes located near a septal region of the right ventricle of the heart near the His bundle, the pacing profile including: a first pulse for delivery via a first electrode located near the septal region of the right ventricle of the heart near the His bundle; and a second pulse for delivery via a second electrode located near the septal region of the right ventricle of the heart near the his bundle, wherein the first and second pulses are at least partially concurrent in time and opposite in polarity to each other; and wherein the implantable pacing profile generator is configured to update an overlap duration of the first and second pulses using a measured effectiveness of a previous electrostimulation provided to the heart via the first and second electrodes located near the septal region of the right ventricle of the heart near the His bundle.
