We diagnosed a 3-year-old girl with acute transverse myelitis (ATM). She presented with weakness of the limbs and developed urination difficulty and respiratory disturbance. Magnetic resonance imaging revealed a symmetric area of high signal intensity on T2-weighted images involving the lower end of the medulla oblongata to the level of the fourth thoracic vertebra. Anti-aquaporin-4 antibody was negative. She was treated with intravenous methylprednisolone pulse therapy, immunoglobulin therapy, and plasmapheresis; however, her clinical symptoms did not change. At 10 and 20days after symptom onset, cardiac arrest occurred on postural change, requiring cardiopulmonary resuscitation. A permanent pacemaker was implanted 23days after onset. In the presence of sympathetic nerve hypofunction, relative hyperactivity of the parasympathetic nerves may have led to severe bradycardia and cardiac arrest in the presence of an inducer, such as a postural change. This is the first reported case of pacemaker implantation for management of ATM.
