Plain-English summary
An 11-year-old male German shepherd was brought in for a heart issue and needed a pacemaker due to a serious heart block that caused a slow heart rate. During the procedure, the dog was given a mix of medications, including ketamine, to keep him comfortable and asleep. However, the pacemaker had to be adjusted because it was moving around too much. For the second surgery, the vet used a lower dose of ketamine, which still worked well for anesthesia. Overall, ketamine proved to be effective for keeping the dog safe and calm during both surgeries.

Abstract
An 11-year-old male German shepherd dog was referred for possible pacemaker implantation. A routine 6-lead electrocardiogram revealed a third-degree atrio-ventricular block with a heart rate of 40 to 45 beats/minute. A transvenous pacemaker implantation procedure was scheduled. The dog was premedicated with 10 µg/kg acepromazine and 5 mg/kg pethidine. A dose of 5 mg/kg ketamine and 0·2 mg/kg diazepam were used for induction and isoflurane in O2 and a constant rate infusion of ketamine (20 to 30 µg/kg/minute) were administered for maintenance of general anaesthesia. Due to a twiddler's syndrome, the pacemaker had to be repositioned. For the second procedure, the same protocol was employed except for a lower dose of ketamine both for induction (3 mg/kg) and constant rate infusion (10 to 15 µg/kg/minute). Ketamine appeared to be useful for both management of anaesthesia and cardiac pacemaker implantation in the absence of a temporary pacemaker.
