1. A system for using with a first lead implanted at or near a first region of a left ventricle (LV) of a heart and a second lead implanted at or near a different second region of the heart, the system comp rising:

  • an implantable medical device (IMD), including;

    a controller circuit configured to;

    program a first pacing vector including a first anode and a first cathode each selected from two or more electrodes on the first lead or one or more electrodes on the second lead, at least one of the first anode or the first cathode selected from the two or more electrodes on the first lead;

    program a second pacing vector including a second anode and a second cathode each selected from the two or more electrodes on the first lead or the one or more electrodes on the second lead, at least one of the second anode and the second cathode selected from the two or more electrodes on the first lead, the second anode different from the first anode or the second cathode different from the first cathode; and

    generate a therapy schedule including an indication of temporal relationship between at least a first pacing sequence and a second pacing sequence; and

    a pacing output circuit coup led to the first and second leads and the controller circuit, the pacing output circuit configured to, in accordance with the therapy schedule, generate and deliver the first pacing sequence according to the first pacing vector, and generate and deliver the second pacing sequence according to the second pacing vector.
