The functional uniformity of the heart and vessels is studied. The idea of the genesis of the carotid sphygmogram from the kinetocardiogram (GS-KCG) was developed on the basis of the analysis of the KCG and carotid-sphygmographic (CSG) pattern obtained in 10 young healthy adults. Two of these examinees were additionally examined under the influence of a s.c. injection of adrenaline (A) and noradrenaline (NA). Two kinds of transducers for the displacement of the chest wall and of the carotid region were used (photoelectric and resonance receiver). They did not touch the skin and were placed in four positions on the thorax; three of them are routine auscultatory positions (ictus, ERB, aorta), one was the carotid artery pulse position. Amplitude and time intervals at rest and under the influence of catecholamines were determined and their interrelationship studied. The amplitudes are more variable than the intervals. The genesis of the waves was studied on the basis of the records in four positions. On this basis, a uniform hypothesis about the genesis of the KCG and CSG waves is derived. From this hypothesis and from the existence of a reflection wave starting at the aorta, the concept of the genesis of the sphygmogram from the kinetocardiogram was developed: the deformation starts at the aorta, is directed to the apex, is there reflected and propagated to the carotid artery. The validity of this concept of the GS-KCG is proved on the basis of experiments with adrenaline and noradrenaline. The quantitative data of peaks and waves from four positions show a stability of the KCG and CSG pattern despite the influence of catecholamines. A comparison is made between the apex cardiogram (ACG) and KCG and determinants of the characteristic pattern of chest movements are given. It was further concluded that the technique of measuring reflection wave velocity (=intracardiac velocity) and pulse wave velocity (=vascular, mixed) can be used as a test for individual reactivity of the cardiovascular system. The wave velocities and the carotid amplitude can help in detecting a disposition towards coronary disease.
研究了心脏和血管的功能统一性。基于对10名年轻健康成年人获得的心动图（KCG）和颈动脉脉搏图（CSG）模式的分析，提出了从心动图生成颈动脉脉搏图（GS-KCG）的概念。其中两名受试者在皮下注射肾上腺素（A）和去甲肾上腺素（NA）的影响下进行了额外检查。使用了两种用于检测胸壁和颈动脉区域位移的传感器（光电和共振接收器）。它们不接触皮肤，放置在胸部的四个位置；其中三个是常规听诊位置（心尖搏动、埃布点、主动脉），一个是颈动脉脉搏位置。测定了静息状态下以及在儿茶酚胺影响下的振幅和时间间隔，并研究了它们之间的相互关系。振幅比间隔更具变异性。根据四个位置的记录研究了波形的起源。在此基础上，得出了关于KCG和CSG波形起源的统一假设。从这个假设以及从主动脉开始的反射波的存在，发展出了从心动图生成脉搏图的概念：变形始于主动脉，指向心尖，在那里反射并传播到颈动脉。通过肾上腺素和去甲肾上腺素的实验证明了GS-KCG这一概念的有效性。尽管受到儿茶酚胺的影响，来自四个位置的峰值和波形的定量数据显示KCG和CSG模式具有稳定性。对心尖心电图（ACG）和KCG进行了比较，并给出了胸部运动特征模式的决定因素。进一步得出结论，测量反射波速度（=心内速度）和脉搏波速度（=血管、混合）的技术可用于测试心血管系统的个体反应性。波速和颈动脉振幅有助于检测冠心病倾向。
