The acute management of infant SVT is debated and often depends on physician preference [9]. In 9-50% of cases, the acute SVT episode ends spontaneously [1, 2, 6, 9, 10] and in 70-90% of patients, adenosine and/or vagal maneuvres (e.g. applying ice pack to the face) work with reasonable success; however, other medications (e.g. amiodarone) may also be required [1, 2, 8, 9]. Once the acute episode is over, the physician and family must make a decision about whether or not to start chronic therapy.
