1. A method for estimating cardiac pressure within a patient using an implantable medical device, the method comprising:

  • applying an electrical field to tissues of the patient including cardiac tissues;

    measuring a parameter influenced by the electrical field;

    inputting default conversion factors for use in converting the measured value to an estimated cardiac pressure value, wherein the default conversion factors are values representative of a correlation between the measured parameter and the cardiac pressure derived from a population of patients; and

    estimating cardiac pressure within the patient by applying the default conversion factors to the measured parameter.
