title: The intrauterine probe electrode.
abstract: An intrauterine probe electrode was inserted into 100 laboring women and 366 bipolar electrode combinations were tested. A noise-cancelling technique was used with the final 28 subjects to remove competing maternal cardiac signals. Twenty-four (86%) had fetal heart rate tracings with sufficient technical quality to allow determination of the baseline fetal heart rate.
