[Heterogeneity of the chemical element composition of the human myocardium after sudden cardiac death].
The content of Si, Fe, S, Ca, Cl in different heart compartments was studied in the autopsy material of human myocardium obtained after sudden cardiac death preceded by emotional stress. Damage of the element content was detected both within the myocardium of one chamber and the whole heart. Zones of high intracellular Ca content were found in the myocardium of the left ventricle and right atrium. Their location coincided with the area of ultrastructural alterations, which were earlier characterized as calcium damage of the myocardium. The same sites were characterized by high Cl content. The size of the areas was determined by roentgenologic mapping. S and Fe content was also different in different heart compartments.
