It is possible to record movement-parameters by means of roentgen videodensitometry of the great central vessels as well the pulmonary artery as the thoracic aorta visible in fluoroscopic image (provided by videorecorder). We could noninvasively measure pre-ejection periods (PEP) for the right heart (PEP f) as well for the left heart (PEP g) by synchronous electrocardiography for each cardiac action and for each examination process. It is important to form a quotient between PEP f and PEP g in the individual case. First findings in patients with cardiac septal defects (with and without right heart block and pulmonary hypertension) show characteristic quotients and figures of the curves. In cases with electrocardiographic left heart block the elongated PEP g can be stated in graduated form. Further investigations on the mechanic interaction between the right and left heart, especially in cases of disorders in the heart conduction system, might be of interest.
通过对荧光图像（由录像机提供）中可见的大中心血管、肺动脉以及胸主动脉进行X线视频密度测定，可以记录运动参数。我们可以通过同步心电图，针对每个心动周期和每个检查过程，无创地测量右心（PEP f）和左心（PEP g）的射血前期。在个体病例中，形成PEP f与PEP g之间的商很重要。心脏间隔缺损患者（有或无右心传导阻滞和肺动脉高压）的初步研究结果显示出特征性的商和曲线图形。在心电图左心传导阻滞的病例中，可以分级显示延长的PEP g。对左右心之间的机械相互作用进行进一步研究，尤其是在心脏传导系统紊乱的情况下，可能会很有意义。
