Plain-English summary
A 9.3-year-old male shorthair cat experienced a temporary heart block while under anesthesia for a procedure related to ear problems. During the surgery, the cat developed a third-degree atrioventricular block, which is a serious condition where the heart's electrical signals are disrupted. The veterinarian treated this by giving the cat a medication to help increase its heart rate. Fortunately, after the anesthesia wore off, the cat's heart rate returned to normal without any further treatment.

CASE DESCRIPTION: A 9.3-year-old, male shorthair cat was evaluated for possible nervous disease resulting from otitis interna. Under propofol and isoflurane anesthesia, this cat developed a third-degree AVB. Isoproterenol was administered by continuous infusion to increase its heart rate. During recovery, heart rate returned to sinus bradycardia together with first-degree AVB without medical treatment. The cause of transient AVB was not observed at the examination. CONCLUSION: The case of this cat suggests that anesthesia can result in a transient third-degree AVB.
