Inappropriate fetal bradycardia
American Journal of Obstetrics and Gynecology, 1984Intrauterine life demands unique respiratory and nutrient mechanisms, and it seems reasonable that some cardiorespiratory responses developed for later extrauterine life would not necessarily be entirely appropriate for the fetal period. In other words, a human fetus may not always be acting in its own best interest when it responds to intrauterine ...

ENDOTOXEMIA CAUSING FETAL BRADYCARDIA DURING UROSEPSIS
Obstetrics & Gynecology, 2001Fetal bradycardia is a recognized response to maternal hypothermia associated with hypoglycemia, tocolysis with magnesium sulfate, or urosepsis, and it is thought to be a direct response to the decrease in the maternal core temperature.A 25-year-old white woman, gravida 1, para 0, at 31 1/7 weeks' gestation was admitted with a diagnosis of ...

Benign Fetal Bradycardias Diagnosed by Echocardiography
American Journal of Perinatology, 1995Five cases of benign fetal arrhythmias presented with dramatic pictures of sustained irregular bradycardias. These cases were not associated with structural heart disease, the development of hydrops fetalis, or maternal autoantibodies. In all but one case, the arrhythmias resolved before delivery.

Urgent Cesarean Delivery for Fetal Bradycardia
Obstetric Anesthesia Digest, 2009To estimate whether fetal bradycardia-to-delivery interval or decision-to-delivery interval was related to cord arterial pH according to different causes of fetal distress.Women who delivered singleton neonates by urgent cesarean delivery because of intrapartum fetal bradycardia were retrospectively categorized into three groups according to the cause ...

Intermittent fetal bradycardia induced by midpregnancy fetal ultrasonographic study
American Journal of Obstetrics and Gynecology, 1989Fetal bradycardias were observed during fetal ultrasonographic and echocardiographic studies performed in the second trimester of pregnancy. The episodes of bradycardia were brief and recovery was usually rapid. Ultrasound transducer pressure applied to the maternal abdomen during the study provoked the phenomenon.

Fetal Bradycardia in Response to Maternal Hypothermia
Obstetrics & Gynecology, 2020BACKGROUND: Fetal tachycardia can occur with maternal fever (hyperthermia); therefore, a low maternal temperature (hypothermia) might produce fetal bradycardia. CASES: Five cases of fetal bradycardia are presented in gestations complicated by maternal hypothermia.

Neuraxial analgesia and fetal bradycardia
Current Opinion in Anaesthesiology, 2005To review the most recent data on labor analgesia and the risk of fetal heart rate changes.Fetal heart rate changes are more common with intrathecal opioids, especially when high doses are used. Intrathecal clonidine seems to increase the risk of hypotension and fetal heart rate changes.

FETAL BRADYCARDIA. A PRACTICAL APPROACH
Fetal and Maternal Medicine Review, 2007Fetal bradycardia may herald fetal demise. This article highlights arrhythmic fetal bradycardia rather than bradycardia caused by perinatal distress. We briefly examine the embryonic conduction system's development and physiology and we review the classification, aetiology, evaluation, and approach to fetal bradycardia.

Irregular Fetal Bradycardia: A Case Report
International Journal of Gynecology & Obstetrics, 1980ABSTRACTThe importance of fetal heart rate patterns in the evaluation of fetal well‐being is discussed in relation to a case of antenatal documentation of a grossly irregular fetal bradycardia in a mother with congenital heart disease. A rare form of conduction disturbance, sinus bradycardia with resultant arterial‐venous dissociation is documented as ...
