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.
Beat-to-beat or short-term variability is the oscillation of the FHR around the baseline in amplitude of 5 to 10 bpm. Long-term variability is a somewhat slower oscillation in heart rate and has a frequency of three to 10 cycles per minute and an amplitude of 10 to 25 bpm.Clinically, loss of beat-to-beat variability is more significant than loss of long-term variability and may be ominous.Small square = 10 seconds; large square = one minute). Interpretation of the FHR variability from an external tracing appears to be more reliable when a second-generation fetal monitor is used than when a first-generation monitor is used.
