Method and apparatus for predicting patient outcomes from a physiological segmentable patient signal

摘要

A method and apparatus for predicting patient outcome from a physiological segmentable signal of a patient. In one embodiment, the method comprises the steps of obtaining the physiological segmentable signal of the patient; segmenting the physiological segmentable signal into a plurality of separate segmentable components; calculating a time series of the morphological distance between adjacent separate segmentable components of the plurality of separate segmentable components; and predicting patient outcome in response to the time series of the morphological distance. In another aspect, the invention relates to a method for extracting information from physiological signals for one or more subjects including the steps of partitioning the physiological signal into a plurality of components, grouping the components into a plurality of information classes, assigning a unique symbol to each information class, mapping each component to the assigned symbol, and examining one or more such sequences for clinical significance.

主权项

1. A method for improving prediction of patient outcome for a specific patient comprising:
obtaining a plurality of patient outcomes and of energy in frequency bands of ECGs for a plurality of prior patients into a database; determining an association of energy in each of the frequency bands with a patient outcome for each of the prior patients using a processor accessing the database; determining the strongest association between energy in one or more of the frequency bands and one of the patient outcomes for each of the prior patients using the processor accessing the database; defining the frequency band with energy with the strongest association with the patient outcome as a diagnostic band for that patient outcome; measuring the energy in the diagnostic frequency band of the specific patient using the processor; and predicting patient outcome for the specific patient in response to energy present in the diagnostic frequency band using the processor.
