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.
There are 2 types of alternators used with external. regulators. One type is a rear terminal and the other is a side. terminal. Current is supplied from alternator-regulator system to. rotating field of alternator through 2 brushes to 2 slip rings. Power. is produced in form of alternating current which is rectified to.
