Validation of Standard and New Criteria for the Differential Diagnosis of Narrow QRS Tachycardia in Children and Adolescents: Erratum

In the article “Validation of Standard and New Criteria for the Differential Diagnosis of Narrow QRS Tachycardia in Children and Adolescents”,¹ which appeared in Volume 94, Issue 51 of Medicine, relevant funding information was originally omitted. Dr. Kukla's name was also misspelled in the text. The article has since been corrected online.
