Neurogenic stunned myocardium (NSM), a syndrome of reversible left ventricu
lar dysfunction best described after subarachnoid hemorrhage, has not been
associated with peripheral neuropathy. We describe a woman with Guillain-Ba
rre syndrome in whom a syndrome compatible with NSM developed in the settin
g of a physiologically documented increase in sympathetic cardiovascular to
ne. This case supports the presumed unifying role of excessive sympathetic
nervous system activation in the pathogenesis of NSM.
