Abstract:
1. 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, the method comprising: sensing ventricular function of the heart; assessing the sensed ventricular function to determine whether a conduction abnormality exists, the assessing including declaring a conduction abnormality to exist when an intrinsic QRS width, measured in the absence of a delivered pacing pulse, exceeds a threshold value of at least 120 milliseconds; providing the ventricular pacing, including at least partially concurrent opposite polarity pacing pulses at a right ventricular septum at or near a bundle of His, in response to determining a conduction abnormality exists; and inhibiting the ventricular pacing, including at least partially concurrent opposite polarity pacing pulses at a right ventricular septum at or near a bundle of His, in response to determining a conduction abnormality does not exist.
