title: Sinusoidal fetal heart rate. II. Continuous tissue pH studies.
abstract: Two cases of SHR in labor monitored by continuous fetal tissue pH measurements are presented. Both showed onset of the pattern in the absence of fetal acidosis, a fall in TpH following the appearance of the abnormal FHR pattern, and fetal compensation with a good perinatal outcome. These patients demonstrate that the fetus may tolerate a SHR and recover from preacidosis and acidosis. Continuous pH measurement may be helpful in conservative management of patients with abnormal FHR patterns.
