1. A method for detecting a likelihood that a patient is experiencing one of several arrhythmias, the method comprising the steps of:

  • (a) acquiring baseline ECG samples, each of which exhibiting an arrhythmia to be detected and a baseline arrhythmia-free ECG sample;

    (b) mapping a reconstructed phase space related to each acquired baseline ECG sample;

    (c) determining at least one equation describing the reconstructed phase space for each acquired baseline ECG sample;

    (d) acquiring an ECG sample to be tested;

    (e) mapping a reconstructed phase space related to the ECG sample to be tested; and

    (f) determining which of the equations most accurately describes the reconstructed phase space related to the ECG sample to be tested.
