Overview
Neurocardiogenic syncope must be distinguished from situational syncope (cough syncope, defecation syncope, micturation syncope, neurally mediated syncope and carotid sinus hypersensitivity). Some patients will have what is called an "atypical" syncope, which is non-neurocardiogenic and without any identifiable triggers.
Situational Syncope
The syncope comes on after cough, defecation, or micturation
Neurally Mediated Syncope
This form of syncope occurs in the context of severe throat or facial pain as occurs in glossopharyngeal neuralgia or trigeminal neuralgia.
Neurocardiogenic Syncope
Syncope following exposure to a noxious stiumulus, fear, or pain is consistent with neurocardiogenic syncope.
Carotid Sinus Syncope
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 neck wear, or tumor compression).
Cardiac Syncope
Occurs due to an arrythmia, and is of abrupt onset and short duration, without any recovery phase.
