Atrial fibrillation (AF) is the most common arrhythmia. It is diagnosed in more than 33 million people worldwide and is the leading cause of hospitalization for arrhythmias. AF is characterized by fast and irregular atrial activation without discrete P-waves at a surface electrocardiography. AF pathophysiological mechanisms are very complex and include the dynamic interaction between arrhythmia substrate and triggers. Consequently, the clinical search for effective therapeutic targets should include the entire process of the onset and progression of the disease: from the first paroxysms to the development of a stable permanent form of AF.

Modern technologies of remote sensing of the Earth from space allow creating new information systems for observing and studying various processes occurring in biogeocenoses and agrocenoses. This is especially important in the case when it comes to the study of grape agrocenoses, since their most important elements are perennial plants and soils that provide a harvest. In this case, it is necessary to create special information technology for monitoring such objects. This will allow forming a series of observations that are uniform in time and space and provide the ability to conduct an analysis with a high degree of reliability in the future. The aim of this work is to develop methodological foundations for the formation of a system for remote diagnostics of soil fertility of grape agrocenoses in connection with the technology of cultivation and bioecological features of cultivated crops in solving problems of improving land use efficiency, as well as the creation of a mock-up of information system for remote monitoring of grape agrocenoses on their basis, aimed at solving tasks of predicting the condition of soils and vineyards, obtaining objective information about predicted fertility, solving problems of increasing land use efficiency, taking into account soil cultivation technologies and bioecological features of cultivated crops, abiotic and biotic factors.

<p>Management of patients with terminal heart failure is one of the most serious ongoing problems in cardiac surgery. In addition, the clinical progression of heart failure is often characterized by cardiac rhythm disturbances, with atrial fibrillation and atrial flutter being the most common types of these disorders. The prognosis may be extremely unfavorable if inappropriate tactics of treatment is used. Development of interventional and minimally invasive surgery expanded the possibilities of treatment of such patients. The article looks at some application features of a hybrid approach to treatment of a patient with atrial flutter and a terminal stage of chronic heart failure.</p><p>Received 3 May 2017.
