title: Refractory fetal supraventricular tachycardia with hydrops: report of one case.
abstract: Fetal tachycardia sometimes is quite difficult to treat, especially when the fetus has congestive heart failure. Sustained supraventricular tachycardia and hydrops had been diagnosed in a fetus as early as the 27th week of gestational age. A variety of antiarrhythmic agents, including digoxin, digoxin in combination with quinidine or propranolol or verapamil, have been prescribed for the mother, always in a vain effort of conversion of the tachycardia. A baby was born via vaginal delivery at 35 weeks' gestation because of premature labor. The tachycardia disappeared immediately after birth, but several episodes of tachycardia occurred during the neonatal period, and were converted only by electric cardioversion or intravenous amiodarone. Oral amiodarone was then prescribed for three months to prevent recurrence. The baby has lived well without attacks during a one-and-a-half-year follow-up.
