Late Decelerations (labor and delivery). A âdecelerationâ describes a decrease in the heart rate of the fetus from its baseline heartrate. âLate decelerationsâ are described as a transient decrease in the fetal heart rate occurring at or after the peak of a uterine contraction. Late decelerations may represent some degree of utero-placental insufficiency. All blood flow in and out of the intravillious space stops briefly during a contraction.
The gestational age of 20â29 days was chosen because the fetal size with a crownârump length of 4â6 cm correlates well with the size of a human embryo at about 10â12 weeks, when selective reduction is often performed2.
