摘要：Syncope is a frequent symptom characterizing a wide group of pathologies with very different prognosis. By this reason, it is necessary a careful risk stratification for a better patient management. For this aim medical history and physical examination are fundamental. Diagnostic exams complete and confirm diagnostic suspiciousness formulated by medical history and examination, but rarely give elements for unexpected diagnosis. Correct identification of pathological mechanism of syncope and determination of associated clinical risk allow the best patient management avoiding dangerous discharge but also, in relation to increasingly limited resources, inappropriate hospitalizations.
