Fetal supraventricular tachycardia: Prenatal diagnosis and pharmacological reversal of associated hydrops fetalis

Intrauterine fetal supraventricular tachycardia is a rare condition often associated with the syndrome of nonimmune hydrops fetalis. When the fetus is preterm it is vital to treat the arrhythmia with maternally administered drugs and different regimens have been reported in the literature. We report 1 case of this arrhythmia successfully treated in utero with maternally administered digoxin resulting in complete reversal of the hydrops fetalis and the birth of a healthy baby. A review of the relevant literature is brought forth.
