1. A method for analyzing ECG signals, comprising:

  • (a) providing at least one ECG signal recorded from a body;

    (b) having a computer determine the value of at least one time-varying parameter of a high frequency band of said ECG signal; and

    (c) having a computer generate an alert responsive to a decision algorithm comprising a set of rules involving a combination of;

    an instant variation of the time-varying parameter value during a test, wherein said instant variation is a change in the parameter value in comparison to the parameter value at a short time before; and

    an analysis of a T-wave abnormality in at least one QRS complex in a low-frequency component of said ECG signal,wherein;

    said analysis of said low-frequency component of said ECG signal is performed in addition to any alignment of high frequency signals from said high frequency band of said ECG signal; and

    said alert comprises indicating ischemia.
