[Radiokinetocardiography: our first experience in studying the movements of the anterior and lateral walls of the left ventricle in patients with myocardial infarct].

: 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.
