Abstract:
1. A medical device, comprising: a sensor module for sensing a plurality of physiological signals a signal grouping module receiving the plurality of physiological signals and grouping the plurality of physiological signals into a plurality of multi-dimensional signals; a plurality of processing modules each receiving one of the plurality of multi-dimensional signals, each of the plurality of processing modules configured to extract a first feature set from the plurality of multi-dimensional signals, perform principal component analysis of the plurality of multi-dimensional signals to compute principal components of variation for each of the plurality of multi-dimensional signals, and extract a second feature set from the principal components; and a controller receiving the first feature set and the second feature set from at least one of the plurality of processing modules, the controller responsive to the first feature set and the second feature set to detect a physiological event, wherein the controller detects the event using a weighted combination of the first set and the second set of extracted features.
