Abstract
For more than 200 years obstetricians have recognized that slowing of the fetal heart in labour may be a sinister sign. For a much shorter period of time, since methods became available for recording fetal heart rate at the bedside, it has been suspected that a substantial decrease in heart rate variability also is sinister. So it is reasonable to ask what light animal experiments have thrown on the subject, and what are the physiological mechanisms which control the heart rate and its variation near term.
