Overview
Neurocardiogenic syncope must be distinguished from situational syncope (cough syncope, defecation syncope, micturation syncope and carotid sinus hypersensitivity.
Situational Syncope
The syncope comes on after cough, defecation syncope, micturation syncope
Assessment of the symptoms and setting may yield clues as to the possible cause of the syncope. Syncope after cough, defecation, and micturition suggests situational syncope; syncope associated with throat or facial pain (glossopharyngeal or trigeminal neuralgia) is indicative of neurally mediated syncope with neuralgia; and syncope after pain, fear, or noxious stimuli suggests neurocardiogenic syncope.4 Carotid sinus syncope may occur with rotation or turning of the head or pressure on the carotid sinus (for example, carotid massage, shaving, tight collars or neckwear, or tumour compression).4
