Does sevoflurane compared with propofol prolong the accessory pathway effective refractory period during electrophysiology assessment?
Does sevoflurane compared with propofol prolong the accessory pathway effective refractory period during electrophysiology assessment?
Sevoflurane may significantly prolong the accessory pathway effective refractory period compared to propofol, which could impact the accuracy of electrophysiology assessments.

Sevoflurane may affect EP assessment accuracy; case report leaves open anesthetic choice in accessory pathway studies.
Sevoflurane has been shown to significantly prolong the action potential duration and the QTc interval. Despite this, clinical studies have shown only minor clinical effects on accessory pathway properties under general anaesthesia with sevoflurane compared with conscious sedation with midazolam. This case demonstrates significant prolongation of accessory pathway effective refractory period (APERP) under general anaesthetic with sevoflurane compared with propofol.
