1. A method for positioning a sensing tip disposed in a ventricle, the method comprising:

  • obtaining an excitation waveform generated by one pair of electrodes disposed on said sensing tip;

    obtaining a conductance waveform sensed by another pair of electrodes disposed on said sensing tip;

    enabling said waveforms to be compared to determine a phase shift between said waveforms; and

    identifying when said phase shift is deemed acceptable due to adjustment of said positioning.
