Late decelerations 2

Late decelerations are characterized by gradual decrease and return to baseline of the fetal heart rate associated with a uterine contraction. The deceleration is delayed in timing, with the nadir of the deceleration occurring after the peak of the contraction. The onset, nadir, and recovery usually occur after the onset, peak, and termination of a contraction. In this tracing, late decelerations have occurred after the first two contractions.
