[Combination therapy for fetal supraventricular tachycardia with flecainide and digoxin].
Persistent fetal supraventricular tachycardia (SVT) with more than 210 bpm frequently leads to congestive heart failure. We report on a case with SVT and congestive heart failure that converted into sinus rhythm within 19 days of therapy with flecainide and beta-acetyldigoxin. A 32-year-old II gravida I para (25 + 1 weeks of gestation) presented with fetal SVT of 267 bpm. ⋯ A healthy boy was born at 38 + 6 weeks of gestation. Although cardioversion is expected after 72 h of therapy according to the literature, this fetus converted into sinus rhythm on day 19 of therapy. This indicates that patients should not be considered resistant to treatment within the first 3 - 4 days.
