[The possibilities of the psychophysiologic eye-hand test in screening cerebrovascular insufficiency]. / Vozmozhnosti psikhofiziologicheskogo testa "glaz-ruka" v skrininge tserebrovaskuliarnoi nedostatochnosti.

The medical and technical basis of the psychophysiological eye-hand test has been developed. The authors' experience with this tool for cerebrovascular insufficiency (CVI) diagnosis has been generalized studying 250 factory workers and 27 patients with vascular encephalopathy. The study has shown the eye-hand test to be a method of screening CVI with sensitivity 91%, specificity 88%, and accuracy 90%.

[Radiokinetocariography--a noninvasive introscopic method of studying the function of the right ventricle in patients with chronic bronchitis]. / Radiokinetokardiografiia--neinvazivnyi introskopicheskii sposob izucheniia funktsii pravogo zheludochka u bol'nykh khronicheskim bronkhitom.

Registration of the reflected SHF electromagnetic waves directed to cardiac chambers served the basis for a new technique of cardiokinetoradiography (CKRG) described in the present paper. The technique promotes a phasic analysis of the right heart (RH) performance, evaluation of the RH anterior wall rate and an indirect estimation of the systolic pressure in the pulmonary artery. Prolonged relaxation including isometric relaxation, elevated Mancini isovolumic index are suggested to be early subclinical signs of the RH dysfunction in patients with chronic obstructive bronchitis. With growing RH insufficiency, changes in the phase structure increase, whereas the velocity of the RH anterior wall motion slows down.

[Radiokinetocardiography: our first experience in studying the movements of the anterior and lateral walls of the left ventricle in patients with myocardial infarct]. / Radiokinetokardiografiia: pervyi opyt izucheniia dvizhenii perednei i bokovoi stenok levogo zheludochka u bol'nykh infarktom miokarda.

Radiokinetocardiography (RKCG), a noninvasive introscopic technique for studying the heart structures by detecting the echoes from the heart of the electromagnetic ultra-high-frequency signal, has been developed. RKCG was used to record the movements of the anterior and lateral walls of the left ventricle in 14 patients with large-focal myocardial infarction localized in the area indicated and in 30 normal persons. The patients were examined at weeks 4-5 of the disease. In patients with myocardial infarction, RKCG permitted one to identify the zones of hypokinesia, dyskinesia (aneurysm), and the transitory zones between the two ones. The use of RKCG makes it possible to discover unequal contractility in the zone of hypokinesia. RKCG appeared to be an informative technique for examining derangements of the movements of the anterior and lateral walls of the left ventricle in patients who suffered myocardial infarction.
