System for characterizing cardiovascular systems from single channel data

A system for detecting a cardiac dysfunction using a computing device, comprising:

• one or more processors;
• and
• a memory having instructions stored thereon, wherein execution of the instructions by the one or more processors, cause the one or more processors to:
• receive only one-dimensional electrophysiological data;
• construct multi-dimensional electrophysiological data from the only one-dimensional electrophysiological data;
• define a phase space system from the multi-dimensional electrophysiological data;
• determine a baseline measurement of a subject's physiological condition from the phase space system;
• determine a first risk score associated with the baseline measurement of the subject's physiological condition;
• apply a therapy to the subject and subsequently receiving only second one-dimensional electrophysiological data;
• construct second multi-dimensional electrophysiological data from the only second one-dimensional electrophysiological data;
• define a second phase space system from the second multi-dimensional electrophysiological data;
• determine a second measurement of the subject's physiological condition from the second phase space system after the therapy is applied;
• determine a second risk score associated with the second measurement of the subject's physiological condition;
• and
• compare the first risk score and the second risk score to determine a utility of patient therapies.

• define a model from the multi-dimensional electrophysiological data;
• detect the cardiac dysfunction from the model;
• and
• provide an indicator of the cardiac dysfunction.
