Opioids have been considered for their hemodynamic stability. Remifentanil is an opioid analgesic with rapid metabolism and fast primary effect and recovery. In this paper, a very rare effect of using remifentanil along with propofol was presented. An 84-year-old male patient with severe aortic stenosis underwent general anesthesia. In order to induce anesthesia and maintain it, fentanyl, pancuronium, and propofol, along with a combination of propofol and remifentanil, were used, respectively. At beginning of remifentanil infusion, bradycardia and then Mobitz type II conduction block with a hemodynamic disorder occurred for the patient. The decreased blood pressure responded to injection of atropine and ephedrine; however, dysrhythmia only improved after cessation of remifentanil. Therefore remifentanil should be used with caution in aortic stenosis.
