Paroxysmal supraventricular tachycardia in the infant.

Paroxysmal supraventricular tachycardia has been noted more frequently in fetuses and newborns since the introduction of monitoring devices. These tachyarrhythmias appear to be well tolerated in the fetus, but in newborns and older infants they may lead to congestive heart failure if allowed to persist for prolonged periods. Wolff-Parkinson-White syndrome is commonly associated with paroxysmal supraventricular tachycardia. The drug of choice in infants is digoxin.
