This week we review a recent report that asks the question, 'Do all infants who present with SVT require preventive anti-arrhythmic medical therapy?' Who might be a candidate for not using an anti-arrhythmia medication in infancy? What sort of parental education is needed to potentially not use medicine and how do patients not treated compare to those who were treated with anti-arrhythmics in regards to re-admission or presentation to the emergency department or development of tachycardia induced cardiomyopathy? How should parents assess their infants for SVT at home? How long should infants be monitored prior to discharge to home after a single uncomplicated episode of SVT? We speak with Assistant Professor of Pediatrics at Washington University and the first author of this week's work, Dr. Anthony Pompa.
