      Baseline fetal heart rate variability is an important parameter in the evaluation of fetal status during the intrapartum period. Prior descriptions of variability have largely been either visual-subjective or stochastic in nature. Unfortunately, correlation between the two has not been substantiated. Sample heart rate tracings were evaluated for variability by a panel of nine experts. Interobserver agreement in the evaluation of variability was high; correlation between visual subjective and stochastic methods was low. The implications are discussed.
