Basilar arterial migraine—a substrate for non-hypotensive syncope

Abstract

AbstractSyncope occurring simultaneously with documented normal blood pressures has been termed “psychogenic” in some patients. Two cases of basilar arterial migraine are presented, both with a diagnosis of syncope and documented normal blood pressures during the syncopal episodes. These findings highlight that syncope seen in the setting of basilar migraine is a variant from the typical form of neurally mediated syncope or cardiac arrhythmia. There is a need to consider the diagnosis of migraine when normal blood pressures and heart rates are recorded during such syncopal episodes.
