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.
Clinical features and incidence. Fetal tachycardia is defined as a heart rate greater than 160-180 beats per minute (bpm). This rapid rate may have a regular or irregular rhythm which may be intermittent or sustained. A sustained fetal tachyarrhythmia is uncommon, affecting fewer than 1% of all pregnancies.
