Answer

A study of asymptomatic children with WPW pattern who underwent EPS for risk stratification reported that a high proportion of subjects experienced sustained AVRT, AF, or both, with the shortest RR between two consecutive preexcited QRSs being 230-250 ms (mean, 237.5 ± 9.6 ms). [5] The authors concluded that those results may be indicative of the necessity of RF ablation in all asymptomatic individuals with WPW pattern.
