1. A method of pacing a patient'"'"'s heart using an implantable lead having a proximal region including at least one proximal electrode positioned in a coronary sinus or great cardiac vein of the patient'"'"'s heart and a distal region positioned in a coronary vein of the patient'"'"'s heart such that at least one of a plurality of distal electrodes is situated proximate an intraventricular septum of the patient'"'"'s heart, the method comprising:

  • sensing an atrial and a ventricular signal of the patient'"'"'s heart via at least one of the proximal electrodes and one of the distal electrodes, respectively;

    determining a pacing threshold associated with each of the plurality of distal electrodes;

    selecting at least one of the plurality of distal electrodes that have associated therewith right and left ventricular pacing thresholds; and

    delivering a pacing signal to the patient'"'"'s heart via the selected at least one distal electrode, the transmitted pacing signal causing a desired contraction of both the right ventricle and the left ventricle.
