AB Electronic  fetal  monitoring  eclipsed  periodic  fetoscopic  auscultation  of  the  fetal  heartbeat  in  the  late  1960s  (Hon,  1958).  It  was  hoped  that  the  continuous  graph-paper  portrayal  of  the  fetal  heart  rate  (FHR),  termed  cardiotocography,  would  reflect  pathophysiological  events  affecting  the  fetus.  Initially,  electronic  FHR  monitoring  was  used  primarily  in  complicated  pregnancies.  Now,  more  than  85  percent  of  all  live  births  in  the  United  States  undergo  electronic  FHR  monitoring  (Ananth,  2013).
