Patent ID: 7359749

Claim:
A medical device for analyzing a physiological signal having variations that define a monodimensional function, said physiological signal having been collected, filtered, sampled and digitized, comprising: means for memorizing the digitized physiological signal in a memory, and processor means for analyzing the memorized physiological signal, comprising: extracting means for decomposing the signal into a plurality of N parameterized bump functions, wherein each bump function is a continuous function having three successive intervals including a first monotonic parameterized function, an affine function, and a second monotonic parameterized function, one of said first second monotonic parameterized functions being an increasing function and the other being a decreasing function; and classifying means for recognizing at least one characteristic parameter of each N parameterized bump function, and allotting to said bump function a standardized label selected from among a plurality of predetermined labels, according to said at least one recognized characteristic parameter; means for storing the standardized label into memory; analyzing means for extracting abnormal signals indicating a pathological event or rhythm disorder from the analysis of said physiological signal; means for transferring said abnormal signals to a computer display such that a physician can make a diagnosis of a condition based on said abnormal signals.
