Key result
Electrical cardioversion restores sinus rhythm in wide-complex infant WPW tachycardia, sustained at ~3 months.
Why the study?
Wolff-Parkinson-White syndrome occurs in neonates and infants with different therapeutic options than in older patients, requiring specific clinical attention.

Highlights the presentation of Wolff-Parkinson-White syndrome with wide QRS complex tachycardia in a very young infant.
Hypothesis-generating for neonatal WPW management; should not yet change practice or guidelines.
Wolff Parkinson White Syndrome occurs due to the presence of accessory pathways that abnormally communicate the atria with the ventricles. It is one of the main causes of paroxysmal supraventricular tachycardia in young people and adolescents, in whom the ideal management is catheter ablation. This syndrome can also occur in younger patients such as neonates and infants, where the therapeutic options are different. We present the case of a 47-day-old patient who was admitted to a public pediatric hospital in Peru due to vomiting. Upon admission, she showed a heart rate of 250 beats per minute; wide QRS complex tachycardia was documented; later, on the electrocardiogram in sinus rhythm, signs of pre-excitation were evident.

Cueva-Parra et al. (2020) conducted a case report in Wolff-Parkinson-White syndrome (n=1). Electrical cardioversion and propafenone was evaluated on Restoration of sinus rhythm. Electrical cardioversion successfully restored sinus rhythm in a 47-day-old infant with Wolff-Parkinson-White syndrome presenting with wide QRS complex tachycardia, who remained asymptomatic on propafenone at 3 months.
