Abstract

A method and a system for monitoring and characterizing a person'"'"'s heart condition for various medically related purposes. The method includes the steps of (a) acquiring a selected person'"'"'s acoustic heart signature, (b) acquiring, substantially simultaneously, that same person'"'"'s electrical heart signature, (c) choosing elements of determined interest from these two acquired signatures and selectively processing and inter- and/or cross-relating such elements, and (d) employing the results of the relating step to create a heart-condition fingerprint useful in the characterization of that person'"'"'s heart condition. From a systemic point of view, that system includes (a) acoustic and electrical data-gathering devices employable to collect acoustic and electrical data from a person, and (b) processing structure operatively connected to these devices, operable to process and inter- and/or cross-relate data gathered by the devices for the purpose of generating a reportable heart-condition fingerprint of a person from whom such data has been collected.

8. A method for aiding in monitoring and characterizing a person'"'"'s heart condition comprising

furnishing invasive data-gathering access to a selected person'"'"'s heart, and

following said furnishing, and utilizing such access, gathering, processing and relating selected portions of, data reflecting that person'"'"'s heart-generated mechanical and electrical behaviors.

9. The method of claim 8, wherein at least said relating step involves utilizing computer processing.

10. A method employing the combined monitoring and characterizing advantages derived from possession of electrical and mechanical heart-activity data for promoting the monitoring and characterizing of a person'"'"'s heart condition in relation to a population of known, different heart afflictions, said method comprising

collecting a body of heart-activity-related electrical data associated with a selected person'"'"'s heart, and recognizing that such electrical data possesses both monitoring and characterizing strengths and weaknesses with regard to a first category of certain ones of such heart afflictions,

collecting, substantially simultaneously, a body of heart-activity-related mechanical data associated with that same person'"'"'s heart, and time-related with respect to such collected electrical data, and recognizing that such mechanical data possesses both monitoring and characterizing strengths and weaknesses with regard to a different, second category of certain ones of such heart afflictions, and

processing and relating, for monitoring and characterizing purposes, such collected electrical and mechanical data bodies in a manner whereby, collectively, the strengths of each data body tend to compensate for the weaknesses of the other data body.

11. The method of claim 10, wherein at least said relating step involves utilizing computer processing.

12. A heart-condition monitoring and characterizing method associated generally with an acute coronary syndrome condition, said method comprising

during a common time frame, collecting (a) a person'"'"'s heart-activity-generated, electrical-functionality signature, and (b) that same person'"'"'s heart-activity-generated, mechanical-functionality signature,

processing such signatures in a manner which includes inter- and/or cross-relating selected components of the two signatures, and

from said processing, generating a binary output which indicates definitively the presence or absence of acute coronary syndrome respecting the person'"'"'s heart.

13. A computer-based heart-condition monitoring and characterizing method comprising

during a common time frame, collecting (a) a person'"'"'s heart-activity-generated, electrical-functionality signature data, and (b), that same person'"'"'s heart-activity-generated, mechanical-functionality signature data,

supplying that collected signature data to a computer, and

using that computer, processing the supplied signature data in a manner which includes at least one of (a) computer-measuring, (b) computer-evaluating, and (c) computer-inter-relating and/or computer-cross-relating, selected components of the two categories of signature data for the purpose of generating a reportable heart-condition fingerprint of a person from whom such signature data has been collected.

14. A method for monitoring and characterizing a person'"'"'s heart condition for various medically related purposes comprising

acquiring a selected person'"'"'s acoustic heart signature,

acquiring, substantially simultaneously, that same person'"'"'s electrical heart signature,

choosing elements of determined interest from these two acquired signatures and selectively processing and relating such elements,
