Annotation. Fainting (syncope) in a given period of life occurs in almost a third of the population, but only in a small number of cases it is a manifestation of a serious disease. The purpose of this observation is to determine the causes of unconscious conditions in young people without a painful history and the absence of any other clinical manifestations and pathological changes in generally accepted laboratory and instrumental examinations. Holter daily ECG monitoring is today considered one of the most important and most effective ways to diagnose heart rhythm disturbances. This article discusses two cases of syncope in young people. The first clinical case occurred in a guy 24 years old. On an outpatient basis, a survey was conducted. All indicators were within the standard values. The patient was diagnosed with Syncopal conditions of unknown origin. When examining the results of ECG monitoring, the cause of syncope was discovered and established. She turned out to be an intermittent form of AV blockade of the II degree of the II type of highly frequent. The patient was recommended to establish an ECS de mand. The second clinical case occurred in a young patient 40 years old. In this patient, with the help of monitoring, a paroxysmal form of ventricular fibrillation was diagnosed. In these two cases, which we examined in this article, only Holter ECG monitoring is of little diagnostic value for verification of syncope in young patients.
