Síncope

Syncope, which can be defined as a transient loss of consciousness caused by transient global cerebral hypoperfusion and characterised by rapid onset, short duration, and spontaneous complete recovery, is a common condition. This definition is useful for differentiating syncope from other clinical conditions that also involve real or apparent transient loss of consciousness, but in which the mechanism is not global cerebral hypoperfusion, such as epilepsy, falls, or psychiatric pseudosyncope. Despite the progress made, the management of patients with syncope remains largely unsatisfactory because of the presence of a significant gap between knowledge and its application. We reviewed the present state of the classification, diagnosis and the diferent therapeutics option of patients with syncope and the necessity of a suitable stratification of risk at the time of evaluating these patients.
