Our survey identified that, among the wide range of medications used to manage infant SVT, the two most commonly used ones are digoxin and propranolol. Digoxin and propranolol are both well established, widely used medications in both infants and adults. Eighty-five percent of survey respondents reported using one or both to manage infant SVT, but did not rationalize their choice nor determine whether one or the other is better to reduce risk of SVT recurrence or whether one is associated with fewer adverse events. Furthermore, pediatric cardiologists and electrophysiologists differed in medication choice.
