[Space-occupying masses in the right atrial cavity. Findings in segmental echo scanning]. / Ob''emnye obrazovaniia v polosti pravogo predserdiia. Nakhodki pri sektoral'nom ékhoskanirovanii.

A total of 1665 patients were examined with the aid of two-dimensional echocardiography scanning. Of these, 3 patients had sizable formations in the right atrium. During scanning, the sizable formations were recorded within the planes of echolocation, whereas the use of one-dimensional echocardiography enabled a sizable formation to be detected but in one patient. In two patients, the sizable formations were mobile and shifted during diastole to the right ventricle. In one patient, the sizable formation was immobile and was detectable only in the right atrium. The mobile formations are likely to be myxomas, whereas the immobile ones are formed by thrombotic masses.

The suggested index of transthoracic impedance time course during loading (20 and 50 V) correlates significantly with the complex index of phase analysis (ratio of the duration of the tension and ejection periods), the stroke and cardiac indices and the QAd index determined by rheography and, at the same time, it is more informative. Its highly significant connection with tolerance to physical load is also noted.
