Listeria meningitis-associated bradyarrhythmia treated with isoproterenol

In the setting of increased intracranial pressure (ICP), various rhythm disturbances have been associated, ranging from tachyarrhythmias to bradyarrhythmias with atrioventricular dissociation. Although most of these observations have been in patients with traumatic brain injuries, it is known that children with acute bacterial meningitis may also have severe intracranial hypertension. We present the case of a previously healthy 2-year-old boy diagnosed with listeria meningitis. Along with clinical signs suggestive of increased ICP and brainstem involvement, our patient had persistent bradyarrhythmia with hemodynamic compromise that was refractory to epinephrine and successfully managed with isoproterenol.
