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

  • an interface for receiving an electrical signal indicating electrical activity of a patient heart over at least one heart beat cycle;

    a signal processor for calculating a signal characteristic value comprising a summation of the square of values of amplitude of said electrical signal relative to a zero voltage baseline of said electrical signal over at least a portion of a heart beat cycle;

    a comparator for comparing the calculated signal characteristic value with a threshold value to provide a comparison indicator; and

    a patient monitor for in response to said comparison indicator indicating the calculated signal characteristic value exceeds the threshold value, generating an alert message associated with the threshold.
