Patent Images
1. A method for detecting arrhythmia from a physiological signal, the method comprising:
- extracting, using processing equipment, a plurality of derived value data sets associated with the physiological signal;
determining, using processing equipment, a plurality of arrhythmia features based on the derived value data sets, wherein the arrhythmia features comprise an entropy feature; and
generating, using processing equipment, an arrhythmia indicator based on the arrhythmia features.

Abstract
Arrhythmia may impact the determination of physiological information from a physiological signal. A patient monitoring system may detect the presence of arrhythmia based on changes in the physiological signal. Derived value data sets may be extracted from the physiological signal and calculations performed to generate arrhythmia features. The arrhythmia features may be used to generate an arrhythmia indicator that may indicate the presence of arrhythmia in the physiological signal.
