1. A method comprising:

  • positioning a pair of current-delivery electrodes in contact with a patient'"'"'s body;

    advancing a multielectrode-bearing delivery device into a coronary sinus and at least partially into a vein of a left ventricle of a patient'"'"'s heart;

    positioning an electrode of the multielectrode-bearing device at an optimal location by;

    delivering current using the pair of current-delivery electrodes to generate a potential field;

    measuring potentials associated with the potential field using an electrode of the multielectrode-bearing delivery device;

    mapping motion of the electrode of the multielectrode-bearing delivery device based on the measured potential; and

    identifying an optimal electrode of the multielectrode-bearing device based on the mapped motion, wherein the location of the optimal electrode corresponds to the optimal location;

    positioning an electrode at the determined optimal location by;

    advancing an electrode-bearing lead along the multielectrode-bearing delivery device; and

    aligning an electrode of the electrode-bearing lead with the optimal electrode of the multielectrode-bearing delivery device;

    after aligning the electrode of the electrode-bearing lead, retracting the multielectrode-bearing delivery device while maintaining the position of the electrode-bearing lead.
