Abstract The aim of the study is to study the acute infectious factor and the role of respiratory viral infections in the formation of left atrial stanning, myocardial contractility and rhythm disorders, and its early diagnosis. Patients showed early signs of left ventricular diastolic dysfunction, changes in valvular apparatus, valvulitis, and carditis. in patients after infectious respiratory disease, diastolic dysfunction is mainly represented by hemodynamic disorders and early stanning of the left atrium (67%). Changes in contractility and rhythm disturbances on the electrocardiogram.
