Artifactual fetal electrocardiographic detection using internal monitoring following intrapartum fetal demise during VBAC trial.

Absent or erratic fetal electrocardiographic signal can result in artifactual electronic fetal heart rate recording. We report a case where detection of maternal heart rate through internal fetal scalp monitor may have masked intrauterine fetal demise secondary to acute uterine rupture during a VBAC trial.
