Graphical user interface and voice-guided protocol for an auscultatory diagnostic decision support system
First Claim
1. A method for detecting a plurality of heart sounds in an auscultatory process comprising the steps of:
- providing a predetermined protocol corresponding with a plurality of recording locations on a patient;
instructing a user to follow the predetermined protocol for recording the plurality of heart sounds at the plurality of recording locations using at least one of a voice guided protocol and a graphical user interface; and
detecting and recording the heart sounds according to the predetermined protocol.

Abstract
The present invention relates to an apparatus and method for determining an auscultatory diagnostic decision. Auscultation of the heart is a well-defined and standard component of physical examinations of patients, however it is a difficult procedure particularly because a stethoscope transfers only a small fraction of the acoustic signal at the chest surface to the listener'"'"'s ears and filters the cardiac acoustic signal in the process. The system assists listeners by implementing a graphical user interface and voice guided protocol to record data and analyze results for the presence of heart sounds and murmurs. The results are identified in terms of standard clinical auscultatory findings which may then be used to make diagnostic and referral decisions.
