A foetal monitor includes a sensing device for measuring uterine movement and foetal heart rate of a patient under observation. A data collection device is coupled to the sensing device and is arranged to receive and sample an output signal of the sensing device and to generate digital signals representative of at least foetal heart rate over a predetermined time interval. The monitor also includes data analysis means including recognition means operable periodically to calculate a baseline heart rate value by calculating a plurality of modal values for a respective plurality of modal ranges of the measured feotal heart rate over a predetermined time interval of the foetal heart rate and to recognize in the digital signals received over a signal link from the data collection device a plurality of predetermined information features by automatically analyzing the digital signals in relation to the baseline heart rate value, and classification means for classifying at least one of the features to produce first output signals representative of the existence of such features and representative of feature classifications. Signal storage means receives and stores the first output signals as a short term knowledge base. Database storage means is providing for storing reference data as a long term knowledge base. The monitor also includes an interference engine arranged to process signals representative of the short term and long term knowledge bases automatically to produce conclusion signals, and indication means arranged to receive the conclusion signals and provide an indication of the conclusion signals.
