Fetal heart rate patterns play a significant role in the modem day obs
tetric care. They also play a significant role in medicolegal allegati
ons of negligence when the fetus suffers injury. Proper interpretation
of the fetal monitor tracing is only one factor in the evaluation of
the reasonableness of obstetric care. Appropriate care and optimal def
ense both derive from reasonable interpretation of pertinent clinical
data, including the monitor strip, along with timely pursuit of a thou
ghtful, properly annotated, plan of care.
