2009年ESC晕厥诊断和处理指南解读（2009 ESC syncope diagnosis and processing guide interpretation） New data on epidemiology were added. After initial evaluation, the new risk stratification method was proposed for cardiac sudden death (SCD) and cardiovascular events. On the basis of extended monitoring, the importance of diagnosis strategy is emphasized. New evidence of evidence-based medicine has been updated. The guidelines are divided into five parts. The first three parts introduce syncope definition, classification, pathophysiological mechanism, epidemiology, prognosis, and diagnosis and treatment. The fourth section describes syncope in particular populations, including the elderly syncope, child syncope, and syncope and driving. The fifth part introduces the mode of diagnosis and treatment of syncope, and emphasizes the importance of multi-disciplinary cooperative diagnosis and treatment. Here is a brief summary of the first three parts. Definition, classification and pathophysiological mechanisms, epidemiology, and prognosis 1 definition Syncope is a T - LOC that is caused by perfusion of the whole brain and is characterized by rapid initiation, short duration and spontaneous complete recovery. Classification and pathophysiological mechanism The t-loc is divided into traumatic and non-traumatic forms. Non-traumatic t-loc includes syncope, epilepsy, psychogenic syncope, and other rare conditions. Therefore, syncope should be noted for the identification of traumatic and non-traumatic other t-loc. According to the pathophysiological mechanism, the syncope is classified as follows: 2.1 reflexive syncope (neuro-mediated syncope) The main result is the excessive reflection of the nervous system that controls the circulation, which causes blood vessel dilation and bradycardia, resulting in decreased arterial blood pressure and total cerebral perfusion. Depending on the trigger factors, it can be broken down into: 2.1.1 vasovagal syncope (VVS), the most common syncope type, mood
