1. A system for determining the cardiac output of a living subject comprising:

  • a plurality of electrode assemblies, each electrode assembly having a plurality of terminals, at least two of said plurality of terminals being spaced from one another by a predetermined distance;

    a current source capable of generating a substantially constant current;

    a plurality of electrical leads connecting said current source with individual ones of said terminals of said electrode assemblies, a circuit for measuring the difference in voltage at said terminals resulting from the flow of said current through said subject and said terminals under varying cardiac conditions of said subject; and

    a circuit for measuring ECG potentials from at least one of said electrode assemblies.
