Plain-English summary
A 3-year-old male crossbreed dog was brought to the vet after suffering blunt trauma to the face. The vet found a fracture in the dog's right zygomatic arch, which is part of the skull. This injury caused the dog to have a slow heart rate and other heart rhythm issues. After giving the dog a medication called atropine, his heart rate returned to normal, and his heart rhythm stabilized. The dog recovered well after treatment.

Abstract
A 3-year-old crossbreed male dog was presented with a history of blunt facial trauma. Skull radiographs showed right zygomatic arch fracture. An electrocardiogram revealed bradycardia, first-degree atrioventricular block and QT prolongation. Standard biochemical profile including electrolytes was normal. Atropine response test (0.04 mg/kg intravenously) restored normal sinus rhythm at a rate of 140 bpm with normal QT and PR intervals. This observation is consistent with oculocardiac reflex secondary to zygomatic arch fracture.
