Abstract
We report the observation of a vaso-vagal syncope (VVS) occurring during lower body negative pressure in a young male volunteer. Recording of the peripheral blood flow, blood pressure and muscular sympathetic nerve activity revealed first a progressive withdrawal of muscle nerve sympathetic activity with redistribution of blood flow before the onset of the VVS.
