title: Change of inhalation anesthetic agents for management of ventricular premature depolarizations in anesthetized cats and dogs.
abstract: Ventricular premature depolarizations (VPD) were found in 27 cats and 14 dogs during inhalation anesthesia. For animals receiving halothane, the anesthetic agent was changed to enflurane (n = 22) or isoflurane (n = 15). After the change to enflurane, the VPD reverted to normal sinus rhythm (n = 19) or decreased in frequency (n = 3). After the change to isoflurane, the VPD reverted to normal sinus rhythm (n = 14) or decreased in frequency (n = 1). For 4 cats receiving enflurane, the inhalant agent was changed to halothane, which caused an increased frequency of VPD (n = 3) or reversion to normal sinus rhythm (n = 1). It was concluded that cats and dogs with VPD during inhalation anesthesia with halothane would benefit from a change to enflurane or isoflurane.
