Hino H, et al. - Researchers tested the validity of a presumption that, compared with propofol, desflurane prolongs the antegrade accessory pathway effective refractory period (APERP) in children undergoing radiofrequency catheter ablation for Wolff-Parkinson-White (WPW) syndrome. It was concluded that desflurane is not suitable for this patient population as it enhances the refractoriness and may block the electrical conduction of the atrioventricular accessory pathway.
