Abstract: An apparatus for achieving a long-term organism signal measurement, for example, an ECG waveform measurement includes measuring means (1) and input means (2) for setting and inputting organism signal analysis data in the measuring means (1). By supplying via the input means (2) organism signal analysis data unique to an organism to be measured into the measuring means (1), there is conducted a learning operation of the characteristics of the organism signals of the subject. Thereafter, the measurement and analysis of the organism signals are achieved for a long period of time by use of the measuring means (1). The measurement is accomplished after the characteristics of the organism signals of the subject are learned, and hence the reliability is increased. In addition, the realtime measurement and analysis are conducted by the measuring means (1) so as to store only abnormal waveforms, which facilitates the judgement thereof to be conducted by a doctor.

Abstract: 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.
