Description
Summary:Wolff–Parkinson–White (WPW) syndrome is a congenital abnormality of the cardiac conducting system. In the general population, its prevalence is 0.15%–0.3%, with supraventricular tachycardia (SVT) being the most common rhythm disorder associated with it. SVT is the most common cardiac arrhythmia in children that requires therapy. It occurs because an accessory conduction pathway allows atrioventricular impulses to reenter the normal conduction pathway, thus completing a circuit that stimulates the atrium and ventricle at a rapid rate. Symptoms are nonspecific but could be life-threatening in infants, necessitating prompt intervention and prophylaxis. Cardioversion by pharmacologic or synchronized direct current (DC) is indicated in life-threatening or refractory arrhythmias. We report a 16-month-old Nigerian girl who had WPW syndrome and developed SVT that required synchronized DC cardioversion.
