Key result
Early-onset infant SVT primarily stems from re-entry mechanisms and undergoes ~80% spontaneous remission.
Why the study?
Supraventricular tachycardia is the most common symptomatic arrhythmia in children, with different types and prognoses according to age, requiring detailed clinical and instrumental characterization.
Population

SVT subtype data in children may guide follow-up; level 4 evidence leaves open validated prognostic models.
Supraventricular tachycardia in infants has a high rate of spontaneous remission (80%) if onset is in the first months of life, and precise diagnosis relies on ECG and occasionally trans-esophageal stimulation.
Vignati et al. (2008) conducted a review in Supraventricular tachycardia (SVT). Supraventricular tachycardia in infants is primarily due to re-entry mechanisms, with spontaneous remission occurring in 80% of cases if onset is within the first months of life.
