Apparatus for analyzing vital signals based upon a feature selected from a plurality of vital signal features

摘要

A vital signal measuring apparatus includes histogram forming device to prepare histograms of a plurality of feature values associated with vital signals, causes a feature value selecting device to select on the basis of a distribution of the histograms, a feature value having information most useful to a vital signal analysis thereby effect a vital signal analysis by an analizing device with considerations of the individual characteristics of subjects. Yet, when a histogram is prepared in a predetermined period of time, accurate judgement and analysis of normality and abnormality in response to changes in a person during a day or between respective examination days can be achieved, and abnormal signals can be easily selected to be stored in a memory.
