Claim One:
1. A method for assisting in a referral indication of heart murmurs, the method comprising the steps of: receiving an acoustic signal representing heart sounds; parsing the received acoustic signal into predetermined physiological events including a plurality of systolic intervals and a plurality of diastolic intervals; computing a first normalized mid-range energy representative of a median systolic interval and a second normalized mid-range energy representative of a median diastolic interval, respectively, the first and second normalized mid-range energies computed from the parsed acoustic signal; characterizing the median systolic interval based on the first normalized mid-range energy by computing a focal point of energy using a maximum first normalized mid-range energy and systolic interval temporal center of a normalized mid-range energy concentration to generate a model of the median systolic interval; determining probabilities relative to a first condition associated with the referral indication and a second condition associated with an absence of the referral indication based on the characterized median systolic interval; and presenting the first normalized mid-range energy, the second normalized mid-range energy and the determined probabilities, whereby the presented first normalized mid-range energy, the second normalized mid-range energy and the determined probabilities may be used to determine whether the referral is indicated.
