early deceleration in fetal heart rate monitoring, a transient decrease in heart rate that coincides with the onset of a uterine contraction. late deceleration in fetal heart rate monitoring, a transient decrease in heart rate occurring at or after the peak of a uterine contraction, which may indicate fetal hypoxia.
DIFFERENCES:   Internal regulators only respond only to the inside, while external  regulators respond only to the outside.   SIMILARITIES:   Both internal and exâ¦ternal regulators can stop their processes.
A voltage regulator is a device (usually an electronic circuit) that controls or maintains the constant voltage output of a power supply. Some (more expensive) DC voltage output power adapters have voltage regulators built in, while most do not.
