What does a sinusoidal pattern mean?

BACKGROUND: In 1972, Manseau et al. and Kubli et al. described an undulating wave form alternating with a flat or smooth baseline fetal heart rate (FHR) in severely affected, Rh-sensitized and dying fetuses. This FHR pattern was called 'sinusoidal' because of its sine waveform.

B.

What is the main cause of a variable deceleration?

Variable decelerations are irregular, often jagged dips in the fetal heart rate that look more dramatic than late decelerations. Variable decelerations happen when the baby's umbilical cord is temporarily compressed. This happens during most labors. Such a pattern can be harmful to the baby.
