US 2005/0033191 A1 · Method and apparatus for detecting a cardiac arrhythmia

Abstract

A method is provided for detecting whether a patient is likely experiencing a cardiac arrhythmia. The method includes acquiring baseline ECG samples that exhibit an arrhythmia that is to be detected, and a baseline arrhythmia-free ECG sample. Each acquired baseline ECG sample is manipulated to determine an equation that describes a reconstructed phase space related to the sample. Next, an ECG sample to be tested is acquired, and a reconstructed phase space is mapped. Finally, it is determined which of the equations most accurately describes the reconstructed phase space of the ECG sample to be tested.

(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.
