Intermittent Sinusoidal Fetal Heart Rate and Massive Maternal-Fetal Hemorrhage: A Case Report

Background: A sinusoidal fetal heart rate pattern is a well-documented sign of maternal-fetal hemorrhage; however, an intermittent sinusoidal pattern is rare. Case: This is a case of a 26-year-old primigravida who presented with decreased fetal movement. On fetal heart rate monitoring there were episodes of intermittent sinusoidal fetal heart rate pattern, and the baby was born with anemia. Conclusion: This case highlights the need for increased vigilance and consideration of a diagnosis of maternal-fetal hemorrhage when an intermittent sinusoidal fetal heart rate pattern is identified.
