Updated: Dec 18, 2014
 

History

Many patients remain asymptomatic. Among those who are symptomatic, the following symptoms and signs could be observed in clinical settings:

  • Recurrent dizziness, near-syncope
  • Recurrent syncope[13]
  • Nonaccidental, unexplained falls[2]
  • Symptoms produced by head turning or wearing garments with tight-fitting collars.
  • Neck tumors, extensive neck scarring secondary to radical dissection or radiation fibrosis or neck trauma
  • Possible prodrome or retrograde amnesia for the syncopal event
  • Symptoms and signs produced when taking carotid pulse or during head and neck surgery

Physical
