Why the study?
Does maternal administration of digitalis convert fetal atrial flutter to normal sinus rhythm?
Does maternal administration of digitalis convert fetal atrial flutter to normal sinus rhythm?
Maternal administration of digitalis can successfully treat fetal atrial flutter in utero, maintaining normal sinus rhythm through delivery.
May support maternal digitalis for fetal atrial flutter; hypothesis-generating case report that leaves open need for controlled trials.
An increased awareness of fetal arrhythmias by obstetricians has resulted in a growing number of diagnosed cases of fetal cardiac problems. A fetus with atrial flutter diagnosed at 31 weeks of gestation was successfully converted to normal sinus rhythm in utero by maternal administration with digitalis. The fetal heart rate stayed in a normal rhythm with a maintenance dose of 0.5 mg/day. The fetus was delivered spontaneously at term and the neonatal heart rate has been in normal rhythm without any medical treatment.
