1. A method for identifying the existence of aortic valve abnormalities in a patient comprising the steps of:

  • (1) providing a non-invasive pressure inducing means for inducing a pressure on a body part of a patient and applying pressure to the body part;

    (2) providing a data receiving means;

    (3) using the data receiving means to receive a stream of pulsation signal data from the patient relating to the pressure response of pulsed fluid flowing through the cardiovascular system of the patient;

    (4) providing a data processing means;

    (5) using the data processing means for processing the stream of pulsation signal data to create an array of pulse wave forms; and

    (6) identifying wave form characteristics that denote the presence of aortic valve abnormalities.
