      The possibilities of up-to-date echocardiographic methods of atria structure and function study are reviewed in the article. The characteristics of advantages and disadvantages, as well as clinical value of traditional and contemporary technologies, in particular tissue Doppler imaging and speckle tracking, are provided. The echocardiographic criteria of changes of atria state in non-valvular atrial fibrillation are described. The attention is payed to role and diagnosis of atrial electromechanical function disturbances and interatrial dyssynchrony in patients with AF.

Key words: atria, structure, function, echocardiography, tissue Doppler, atrial fibrillation, myocardial deformation, interatrial asynchrony.
