THE ROLE OF RANDOM OSCILLATIONS OF CARDIOVASCULAR VARIABLES

The field of chronobiology mainly is concerned with rhythms of different frequency, like circadian, circaseptan, circannual etc. (1). Although most periodic events are composed of periods of activity and periods of rest, or of periods of higher and lower activity, it appears that the term delay was so far, until recently, not yet of particular interest. There are two reasons why a short introduction to the chronobiological and chronopathological aspects of delay appear to be of interest.
