Giant negative T waves in Guillain–Barré syndrome
Abstract:A Guillain–Barré syndrome patient showed giant negative T waves on electro‐cardiography at the height of the disease, with large left ventricular hypokinesis on echocardiography and extensive defects on 123I‐meta‐iodobenzylguanidine myocardial scintigraphy. Gamma‐globulin improved the neurological symptoms, and the above abnormalities resolved. We speculate that cardiac sympathetic nerve endings were transiently damaged, with consequent myocardial injury, due to norepinephrine toxicity.
