1. A method for determining a cardiac function associated with a subject, comprising the steps of:

  • determining base anatomical characteristics associated with the subject;

    determining pulse delay to a first body site (PD01) and a second body site (PD02) as a function of the anatomical characteristics, wherein the distance via the arterial tree from the aortic valve to said first body site (PD01) is different than the arterial tree distance from said aortic valve to said second body site (PD02);

    determining pulse wave velocity between said first body site and said second body site (PWV12);

    determining pulse wave velocity between said aortic valve and said first body site (PWV01) as a function of said PWV12, and said anatomical characteristics; and

    determining the pre-ejection period (PEP) as a function of said PD01 and PWV01.
