Matrix-Based Patient Signal Analysis

摘要

Disclosed herein is a framework for facilitating patient signal analysis. In accordance with one aspect, the framework generates a signature cycle matrix corresponding to a single cycle of the patient signal data by segmenting the patient signal data into multiple portions. The signature cycle matrix may further be segmented into sub-matrices corresponding to different levels. Properties of the sub-matrices may then be determined to generate diagnostic results.

主权项

1. A system for patient signal analysis, comprising:
a patient monitor configured to acquire a patient signal data from a patient; and a computer system communicatively coupled to the patient monitor, wherein the computer system includes
a non-transitory memory device,a processor device in communication with the memory device, anda signal analysis unit stored in the memory device and operative with the processor device to perform steps including
generating a signature cycle matrix corresponding to a single cycle of the patient signal data by segmenting the patient signal data into multiple portions,segmenting the signature cycle matrix into sub-matrices corresponding to different levels,determining properties of the sub-matrices,determining a sequential energy index based on the properties of the sub-matrices, andcharacterizing an abnormality based on the properties and the sequential energy index.
