Clinical presentations of lateral medullary stroke vary. Wallenberg syndrome is the most common presentation, which includes vertigo with nystagmus, ataxia, ipsilateral sensory deficits in the face, bulbar muscle weakness, and ipsilateral Horner’s syndrome. The nucleus tractus solitarius, the dorsal vagal nucleus, and the nucleus ambiguous in the lateral medulla oblongata play a critical role in autonomic regulation and have centers for respiratory, cardiac, and vasomotor reflexes. Despite this, cardiac arrhythmias such as asystole are a rare clinical manifestation of lateral medullary stroke.
