1. A multiple monopolar system for measuring the stroke volume of a patient'"'"'s heart, comprising:

  • an intracardiac impedance catheter having a distal end and a proximal end;

    a plurality of same-polarity-monopolar electrodes axially spaced along the surface of said distal end of said impedance catheter;

    a reference electrode adapted for positioning distant from said monopolar electrodes in the patient'"'"'s body; and

    monopolar means for supplying a drive signal and measuring impedance between each of said monopolar electrodes and said distant reference electrode.
