Cardiac effects of acute myelitis

Neurogenic stunned myocardium has been described in association with subarachnoid hemorrhage, Guillain-Barre syndrome, and metastatic brain tumors. We describe a case of neurogenic stunned myocardium associated with acute myelitis. A 27-year-old female presented with acute onset of quadriplegia, sensory deficit, and acute pulmonary edema. Magnetic resonance imaging was consistent with acute myelitis. Echocardiogram showed left ventricular ejection fraction of 35% with moderate to severe global hypokinesis. During the course of admission, she had several episodes of sinus bradycardia and high degree atrioventricular block. All cardiac abnormalities resolved completely in eight days of admission.
