Roentgenometric analysis of morphological changes of the heart was made in 114 healthy individuals and 192 patients with diffuse toxic goiter living in the Tien Shan mountains. It is shown that the main dimensions of the heart and Moore's index pointing to pulmonary hypertension increase as the disease advances and is more marked in the people living in high altitudes. Diastolic and systolic volumes of the heart in patients with diffuse toxic goiter show a statistically significant increase (p less than 0.

Since these curves of motion widely correspond to the central curves of the arterial pulse it is possible to state systolic time intervals separately for the right and left heart. Analogically to the presphygmic index after Rentsch with global evidence on the left-ventricular function of the heart these are possible for the outflow way of the right ventricle, also by formation of the quotient of the electrokymographically established STI.

No differences could be ascertained between hypertonic and normotonic patients with ill vessels. In the patients compared with the clinically healthy test persons we registered surface-kymographically and electrokymographically more frequently a pathological marginal movement of the heart as a reference to a myocardial dysfunction.

Methods of arterial sphygmography were applied for studying the vessels of the systemic circulation, while electrokymography was used for the pulmonary circulation.
