STUDY OF RISK FACTORS THAT CAN INFLUENCE THE EVOLUTION OF PEDIATRIC PATIENTS DIAGNOSED WITH WOLF PARKINSON WHITE SYNDROME

Abstract

Cardiac arrhythmias in children and young are presented in a broad spectrum, given the large and varied number of known arrhythmias. The incidence of pre-excitation syndromes in children ranges from 1:250 to 1:1000 [11].Our understanding of ventricular preexcitation began in 1921 when Wedd described an “intraventricular block and a PR interval of 0.08 ms.” [1] Wolff-Parkinson-White (WPW) was first described in 1930 as a bundle-Branch Block with Short P-R Interval. Moreover, the delta wave Wolff et al. described the presence of the delta wave on the EKG for the first time [2].Clinical manifestations in WPW are broad, ranging from recurring PSVT to SCD. The risk of developing the last condition in people with WPW syndrome is still unknown. However, multiple studies reveal that asymptomatic WPW has a low chance of SCD and a favorable prognosis [3-6]. Moreover, multiple studies present reasonable life expectancy in patients with WPW syndrome, even if they may present multiple episodes of PSVT [7-10].
