title: [Use of sympathomimetic agents in fetal atrioventricular heart block].
abstract: A healthy pregnant was referred at 34 weeks gestation because an obstetrical ultrasound examination had shown fetal bradycardia and nonimmune hydrops. The heart was anatomically normal but complete heart block was present with a ventricular rate of 22bpm and atrial of 101bpm. We injected isoproterenol by cordocentesis direct in the umbilical vein of the fetus and a significant increase into the ventricular and atrial rates were obtained. The direct therapy with sympathomimetic drugs is a simple technique and may save fetuses with complete heart block and hidrops.
