“Syncope PLUS” syndromes = high risk
+ headache = SAH or ICH
+ neuro deficit = stroke/TIA or ICH Syncope
+ confusion = seizure
+ chest pain = MI, PE, or aortic dissection
+ back/abdominal pain in elderly = AAA or thoracic dissection if upper back
+ pregnancy = ectopic
-exertional syncope = dysrhythmia (tachycardia- or ischemia-induced) or cardiac output obstruction
Also noncardiogenic causes, for example neurologic syncope (includes SAH, brainstem ischemia, and basilar artery migraine).
