1. A method of analyzing cardiac functions in a subject, the method including, in a processing system:

  • a) causing one or more electrical signals to be applied to the subject using a first set of electrodes, the one or more electrical signals having a plurality of frequencies;

    b) determining an indication of electrical signals measured across a second set of electrodes applied to the subject in response to the applied one or more signals;

    c) for a number of sequential time instances;

    i) determining from the indicating data and the one or more applied signals, an instantaneous impedance value at each of the plurality of frequencies;

    ii) determining, using the instantaneous impedance values, an intracellular impedance parameter; and

    ,d) determining, using the intracellular impedance parameter over at least one cardiac cycle, one or more parameters relating to cardiac function.
