Features of diagnosis and treatment of newly diagnosed atrial fibrillation

Due to the wide spread in the population and high risk of complications, atrial fibrillation is an important nosology, and  doctors of both outpatient and hospital departments should be prepared for its early detection and diagnosis. The absence of  specific symptoms and clear causes of onset, as well as the many associated clinical conditions, mean that knowledge of atrial  fibrillation, especially its debut — the first diagnosed atrial fibrillation — is particularly necessary for general practitioners.  This article analyzes literature on first diagnosed atrial fibrillation, focusing on the peculiarities of the disease’s course,  diagnosis, choice of tactics, and treatment. The article introduces readers to information from modern publicly available  publications on this topic, providing an overview of the key stages in the historical development of medicine in this area.  Based on literary sources, existing problems of underestimating the danger of the disease, lack of unified approaches to patient  management, and key definitions and concepts are revealed today.
