Обморок – кратковременный эпизод нарушения сознания, сопровождающийся утратой постурального тонуса и в большинстве случаев приводящий к падению пациента. Причина обмороков – остро возникшее нарушение перфузии головного мозга. Выделяют нейрорефлекторные, кардиогенные и ортостатические обмороки. В статье рассматриваются основные клинические варианты обмороков, вопросы диагностики, дифференциальной диагностики обмороков с другими пароксизмальными состояниями несинкопальной природы, алгоритм диагностики пациентов с пароксизмальными состояниями.
Fainting is a short-term episode of impairment of consciousness, accompanied by a loss of postural tone and in most cases leading to a fall of the patient. The cause of syncope is an acute abnormality of the perfusion of the brain. There are neuroreflex, cardiogenic and orthostatic faints. The main clinical variants of syncope, diagnosis, differential diagnosis of syncope with other paroxysmal conditions of non-syncopal nature, algorithm for diagnosing patients with paroxysmal conditions are examined in the article.
