US Patent 8010192 Endocardial pacing relating to conduction abnormalities

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.
