Electronic feta l heart rate (FHR) monitoring was introduced in the late 1960s with the hope of preventing intrapartum fetal brain injury and cerebral palsy (CP). However, it is now clear that this hope was unrealistic for at least 2 reasons. First, the false-positive rate of intrapartum FHR monitoring for predicting CP exceeds 99%. Except in the most extreme cases, intrapartum FHR monitoring has never been capable of reliably predicting CP.
