[Studies of the motion of the anterior heart wall and central arteries using radiokinetocardiography].

A total of 21 subjects without signs of circulatory abnormalities were examined by a noninvasive intrascopic cineradiocardiographic technique which involved recording of an electromagnet superhigh-frequency signal reflected from the heart and central arteries. The oscillations occurred in the initial segment of an echo signal were explored. Cineradiocardiography was demonstrated to allow the motions of the arterial wall of the ventricles, atria, and a proximal portion of central arteries to be studied.

[Radiokinetocariography--a noninvasive introscopic method of studying the function of the right ventricle in patients with chronic bronchitis].

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.
