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.
针对心脏腔室的反射超高频（SHF）电磁波的记录是本文所述心脏动态放射成像（CKRG）新技术的基础。该技术有助于对右心（RH）功能进行阶段性分析，评估右心前壁速率，并间接估计肺动脉收缩压。包括等长舒张在内的延长舒张期、升高的曼奇尼等容指数被认为是慢性阻塞性支气管炎患者右心功能障碍的早期亚临床征象。随着右心功能不全加重，相位结构变化增加，而右心前壁运动速度减慢。
