Abstract
Supraventricular tachycardia (SVT) is the most prevalent arrhythmia observed in infants, impacting individuals with or without congenital cardiac dysfunction. Infantile-onset SVT typically manifests within the initial one to two months of life. A variety of anti-arrhythmic medications are employed to treat SVT in infants during their first year of life. Nevertheless, a consensus has yet to be reached on the most efficacious drug, and treatment approaches continue to vary considerably As SVT remains a frequent problem around the world, with different management approaches and no obvious optimal option, we conducted a systematic review of the new update of antiarrhythmic drugs for managing SVT in infants under one year old.
