The spatial closed signal pattern is represented by measured signals picked up from a living being by means of electrodes. Sequences of consecutive spatial slope values are formed for each spatial closed signal pattern and different such sequences associated with different spatial closed signal patterns are mutually correlated. As a result of such correlation, the sequences are classified according to different classes and there is determined a temporal offset between such sequences. Minimum spatial slope values respectively associated with the starting region and the end region of each sequence are determined for each class. Predetermined time intervals about the moments of time which are associated with such minimum spatial slope values, are investigated for those sampling moments of time associated with the measured data having the smallest mutual spatial distance. The moments of time at which these measured data appear, constitute the starting point and the end point of the related spatial closed signal pattern.
A method of determining the starting point and the end point of a spatial closed signal pattern in a time sequence of individual ones of such spatial closed signal patterns, each of which is constituted by a series of signals measured at predetermined moments of time, said method comprising the steps of:
