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.
