The patients were divided into the following groups: group 1, with injury of the upper respiratory tract; group 2, with bilateral pneumonia (C\u04221, 2), and group 3, with severe pneumonia (C\u04223, 4).

In patients with moderate pneumonia, early peak diastolic velocity (p=0.09), right ventricular isovolumic diastolic time (\u0440=0.09), and pulmonary artery systolic pressure (\u0440=0.005) where decreased, while tricuspid annular peak systolic velocity was, in contrast, increased (\u0440=0.042). Both segmental systolic velocity of the LV mid-inferior segment (\u0440=0.006) and the mitral annular Em\u200a\/\u200aAm ratio were decreased. In patients with severe disease at 6 months, right atrial indexed volume was reduced (\u0440=0.036), tricuspid annular Em\u200a\/\u200aAm was decreased (\u0440=0.046), portal and splenic vein flow velocities were decreased, and inferior vena cava diameter was reduced. Late diastolic transmitral flow velocity was increased (\u0440=0.027), and LV basal inferolateral segmental systolic velocity was decreased (\u0440=0.046). In all groups, the number of patients with heart rhythm disorders was decreased, and parasympathetic autonomic influences prevailed.\n                  <\/jats:p>\n                  <jats:p>\n                    <jats:italic>Conclusion\u00a0\u00a0\u00a0\u00a0\u00a0<\/jats:italic>\n                    At 6 months after coronavirus infection, practically all patients noted improvement of their general condition; incidence rate of arrhythmia and cases of pericardial effusion were decreased; and autonomic nervous system activity recovered. In patients with moderate and severe disease, morpho-functional parameters of the right heart and the hepatolienal blood flow were normalized, however, occult disorders of LV diastolic function remained, and LV segmental systolic velocity was reduced.\n                  <\/jats:p>","DOI":"10.18087\/cardio.2023.2.n1973","type":"journal-article","created":{"date-parts":[[2023,3,7]],"date-time":"2023-03-07T03:36:26Z","timestamp":1678160186000},"page":"27-33","source":"Crossref","is-referenced-by-count":0,"title":["Cardiohemodynamic Changes and Cardiac Arrhythmias After Coronavirus Infection"],"prefix":"10.68900","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6280-0757","authenticated-orcid":true,"given":"M.
