1. A system for heart performance characterization and abnormality detection, comprising:

  • an interface for receiving a signal representing electrical activity of a patient heart occurring during individual heart cycles of a plurality of sequential heart cycles;

    a signal processor for,decomposing the received signal into a plurality of signals comprising a heart cycle signal primary wave and one or more heart cycle signal wavelets occurring at corresponding successively higher frequencies anddetermining a plurality of amplitude representative values of said heart cycle signal primary wave and said one or more heart cycle signal wavelets;

    a comparator for comparing said plurality of amplitude representative values with a corresponding plurality of predetermined threshold values; and

    a patient monitor for in response to the comparison indicating at least one of said amplitude representative values exceeds a respective predetermined threshold value, generating an alert message associated with the respective predetermined threshold.
