Method and apparatus for detecting a cardiac arrhythmia
First Claim
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.

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.
