SYSTEMS AND METHODS FOR TUNING, ANALYSIS AND DISPLAY OF HEART SOUNDS
First Claim
1. A method for tuning and displaying heart sounds of a patient, the method comprising:
- sensing heart sounds from at least one chest location of the patient;
transducing the heart sounds into electrical signals;
tuning the electric heart signals, wherein the tuning of the electric heart signals includes extracting useful pathology information; and
displaying at least one of the electrical heart signals, the tuned electric heart signals and the extracted pathology information.

Abstract
A tunable auscultation system includes a heart sound acquirer for sensing heart sounds from at least one chest location of the patient. An initial conditioner then conditions the heart sounds through pre-amplification and anti-aliasing. The heart sounds are transduced into electrical signals by a signal processor. The electric heart signals are then tuned by an analysis tool. The analysis tool includes an interaction tuner, a processing tuner and an output tuner. The interaction tuner includes a preset tuning selector and a dynamic range tuning selector. The processing tuner includes a band pass filter and an algorithmic extraction engine which applies extraction algorithms to the electric heart signals, segments them and extracts signals of interest. Signals of interest may be correlated to specific pathologies. The output tuner includes a signal strength indicator, a diagnosis indicator, an overlapping cardiac cycle display and a display configuration engine. A display module provides output.
