The patient is experiencing uterine tachysystole, which is defined as more than five contractions in 10 minutes, lasting longer than 90 seconds, or with less than 30 seconds of interval between contractions. This can cause fetal hypoxia and distress, as evidenced by late decelerations in the fetal heart rate tracing.
