24 Possible Causes for Fetal Bradycardia, First Trimester Bleeding

  • Threatened Abortion

    CONCLUSIONS: First trimester bleeding with visible fetal heart beat appears to associate significantly with higher subsequent spontaneous abortion rate than those without.[] Some features suggestive of a poor outcome: fetal bradycardia : small mean gestational sac diameter large and calcified yolk sac of more than 7 mm small or irregular gestational[] Epidemiology Prevalence : First Trimester Bleeding in 25% of pregnant women III.[]

  • Abruptio Placentae

    If significant placental separation is present, the fetal heart rate tracing typically shows evidence of fetal decelerations and even persistent fetal bradycardia.[] The appearance of HFUC with vaginal bleeding in the third trimester of pregnancy should make the obstetrician highly suspicious of abruptio placentae.[] Spotting (during first and second trimester) Bleeding that is sudden, profuse and PAINLESS (during end of second trimester, or during third trimester) Note: Bleeding may occur[]

  • Pregnancy

(2010, August).[] However, in the situation where intervention is recommended in the interests of the fetus (e.g. fetal bradycardia), the issue of best interests is less clear.[] First trimester bleeding.

  • Fetal Distress in Labor

    Some level of spotting during pregnancy may be normal and often occurs when a fetus implants to the uterus during the first trimester.[] These warning signs include: Fetal Tachycardia ( 160); Moderate Fetal Bradycardia (100-120) with lost variability ; Absent beat-to-beat variability (STV); Marked Fetal Bradycardia[] The correlation between fetal bradycardia area in the second stage of labor and acidemia at birth.[]

  • Preterm Labor

  • Alobar Holoprosencephaly

    INTERVENTIONS: A cesarean section at 38 weeks was indicated for fetal bradycardia and a female baby was delivered, with Apgar score 6, weight 2290g.[] Some believe that there may be a genetic component, but non-genetic risk factors include gestational diabetes, first trimester bleeding, drug and alcohol use, and prior miscarriage[] trimester bleeding and dizygotic twinning. [1] Alobar holoprosencephaly is characteristically presents with a monoventricular cavity, fused thalami and absence of midline[]

  • Stroke

  • Labor and Delivery Complication

    Fetal bradycardia is defined as a baseline rate of less than 110 beats per minute; fetal tachycardia is defined as a baseline rate of more than 160 beats per minute. 19 Variability[] We observed independent associations between uterine leiomyomas and abruptio placentae (OR 3.87, 95% CI 1.63, 9.17), first trimester bleeding (OR 1.82, 95% CI 1.05, 3.20),[] BAD fetal heart rate pattern (bradycardia most common - also variable decelerations where Consequences of uterine rupture?[]

  • Fetal Erythroblastosis

    Two intraperitoneal transfusions and one intracardiac transfusion were given within three days but fetal erythroblastosis still progressed to fetal bradycardia and occasional[] First trimester bleeding is any vaginal bleeding during the first 3 months of pregnancy.[] bradycardia, cord hematoma, umbilical vein compression, and fetal death have been reported during IVT.[]

  • Pregnancy-induced Hypertension

    First trimester bleeding is any vaginal bleeding during the first 3 months of pregnancy.[] Choice of drug: Fetal bradycardia following administration of lidocaine, mepivacaine, and prilocaine.
