Method and system of monitoring cardiac function based on patient position

A system for monitoring cardiac function of a patient, the system comprising:

• an electrocardiograph monitor configured to record cardiac waveform data from the patient;
• at least one position sensor configured to sense a position of the patient and produce a position input;
• a processor;
• a position analysis module executable on the processor to:
• receive the position input;
• determine a position class based on the position input, wherein the position class is one of a predefined set of position classes;
• output the position class;
• a waveform analysis module executable on the processor to:
• receive the cardiac waveform data;
• determine whether model waveform parameters are established for the position class;
• establish new model waveform parameters for the position class if none exist;
• compare the cardiac waveform data to model cardiac waveform parameters for the position class to determine a cardiac status of the patient;
• and
• output the cardiac status.

A non-transitory computer readable medium having computer-executable instructions stored thereon, wherein the instructions include steps comprising:

• receiving a position input from a position sensor attached to the patient;
• classifying the position input into a position class, wherein the position class is one of a predefined set of position classes;
• receiving cardiac waveform data for the patient;
• determining whether model waveform parameters are established for the position class;
• establishing new model waveform parameters for the position class if none exist;
• and
• comparing the cardiac waveform data to model cardiac waveform parameters for the position class.
