Why the study?
Can features at presentation or initial esophageal EP study predict which infants with SVT will not require medication or have inducible SVT at 1 year?
Population
33 infants aged 3 months or younger who presented with supraventricular tachycardia (SVT)

Infant SVT prognosis cannot be predicted from presentation or initial esophageal EP study; leaves open need for better risk-stratification tools.
Can features at presentation or initial esophageal EP study predict which infants with SVT will not require medication or have inducible SVT at 1 year?
While clinical episodes of SVT become uncommon by 1 year of age in infants, most still have inducible SVT, and initial clinical or EP features do not predict this course.
Etheridge et al. (1999) studied this question.
