First Claim
Patent Images
1. A system, comprising:
- a sensor configured to sense a ventricular function of the heart;
a processing circuit configured to determine whether a conduction abnormality exists using information about the ventricular function of the heart obtained via the sensor;
an electrostimulation circuit configured to generate ventricular electrostimulation in response to a determination by the processor circuit that a conduction abnormality is present, the ventricular electrostimulation for delivery at or near a bundle of His via at least two electrodes and including at least partially concurrent opposite polarity electrostimulation pulses;
wherein the processing circuit is configured to determine whether the conduction abnormality exists by using at least an electrogram fractionation.

Abstract
Various systems, methods and arrangements are implemented in connection with ventricular pacing. One such method relates to a method for use in connection with ventricular pacing of a left ventricle of a heart from a pacing lead located in the right ventricle. Ventricular function of the heart is sensed. The sensed ventricular function is used to determine whether a conduction abnormality exists. The ventricular pacing is provided in response to determining a conduction abnormality exists and the ventricular pacing is inhibited in response to determining a conduction abnormality does not exist.
