System for ventricular function abnormality detection and characterization

A system for heart performance characterization and abnormality detection, comprising:

• an interface configured to receive signal data representing an electrical signal indicating electrical activity of a patient heart over a plurality of heart beat cycles;
• a filter configured to extract first signal component data in a first selected bandwidth and first heart cycle portion of the received signal data and second signal component data in a different second selected bandwidth and second heart cycle portion of the received signal data;
• a signal processor configured to:
• determine a first value based on the first signal component data, the first value comprising a first energy value derived from the first signal component data or a first entropy value derived from the first signal component data, and
• determine a second value based on the second signal component data, the second value comprising second energy value derived from the second signal component data or a second entropy value derived from the first signal component data;
• calculate a ratio of the first value to the second value;
• and
• a patient monitor configured to generate, in response to comparing the calculated ratio or value derived from the calculated ratio with a threshold value, an alert message associated with the threshold.
