Normal fetal heart rates may mask JET; case reports leave open optimal prenatal detection and foramen ovale associations.
Katsura et al. (2022) conducted a case report in Fetal junctional ectopic tachycardia (n=9). Antiarrhythmic therapy (flecainide, amiodarone, sotalol, digoxin) was evaluated. Fetal junctional ectopic tachycardia can present without tachycardia and should be suspected in fetuses with ventriculo-atrial dissociation and signs of hemodynamic deterioration.
