| Summary: | Introduction: Short-term maternal administration of betamimetics is a common obstetric practice with uses including tocolysis during antenatal corticosteroid administration for fetal lung maturity, intrapartum tachysystole, and prior to external cephalic version. While previous research has demonstrated adverse effects of prolonged use of maternal betamimetics, no prior documentation exists of fetal tachyarrhythmias beyond sinus tachycardia after administration of terbutaline. Case: This case documents a transient fetal tachyarrhythmia consistent with presumed atrial flutter after maternal administration of terbutaline for external cephalic version. On day of life 9, the neonate presented in supraventricular tachycardia with signs of heart failure and was subsequently diagnosed with Wolff-Parkinson-White syndrome. Conclusion: Maternal administration of terbutaline may be associated with transient fetal tachyarrhythmia. In some fetuses, this cardiac arrhythmia may predate diagnosis of an underlying cardiac disorder, warranting close follow-up after delivery. |
