MATA CUEVAS, Lázaro A. et al. Atrial fibrillation by accessory pathway with pattern of ventricular pre-excitation: A case report. CorSalud [online]. 2020, vol.12, n.3, pp.338-342.  Epub 01-Sep-2020. ISSN 2078-7170.

Atrial fibrillation by accessory pathway is a dangerous disease that can cause sudden death, it is rare and it needs a careful management, even more, if a pattern of ventricular pre-excitation appears. The case of a white skin 17-year-old teenager with a history of short palpitations at moderate effort, and occasional loss of consciousness of short duration, without other associated symptoms, is presented. At the moment of admission, he presents palpitations, fatigue, pallor and low blood pressure; in the electrocardiogram a tachycardia with wide, irregular QRS, with delta wave and rapid ventricular rate is observed, which was interpreted as pre-excited atrial fibrillation. Synchronized electrical cardioversion to QRS with 100 joules was performed, and sinus rhythm was restored with electrocardiographic pattern of ventricular pre-excitation (Wolff-Parkinson-White syndrome).

Palabras clave : Atrial fibrillation; Syncope; wide QRS complex tachycardia; Ventricular preexcitation.
