oa Central African Journal of Medicine - The carotid sinus syndrome - another unrecognised disorder

Volume 29, Issue 5
  • ISSN : 0008-9176



A case is presented of a male, age 67 years, suffering from recurrent attacks of loss of consciousness (LOC) over a period of fifty years, undiagnosed despite repeated intensive examinations in many major world medical centres. The performance of a simple bedside test, carotid sinus massage (CSM) induced sudden hypotension, bradycardia, transient asystole and a blurring of consciousness, disclosing a very sensitive left carotid sinus, the cause of his life-long disorder. The carotid sinus syndrome (CSS) is easily and simply diagnosed, and CSM should form an integral part of the examination in elucidating the cause of transient recurrent loss of consciousness.
