<unk>  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.
