[Size of cardiomyocytes of the left portion of the heart in adults].
As demonstrates the investigation of cardiomyocytes of the left cardiac parts performed in 16 practically healthy mature persons died in accidents, the average area of the cells projections in the auricular atria makes 644 +/- 15 mcm2, and the portion of the multinuclear cells--2.27%. In the ventricular wall and in the papillar muscle these parameters are 831 +/- 16, 700 +/- 30 mcm2 and 11.25, 12.62%, respectively. Distribution of nuclei in the cardiomyocytes of all the cardiac zones studied is characterized by a predominance of tetra-, hypertetra- and octaploid classes, therefore the average amount of DNA in the nuclei reaches certain high values. Differences in size of the cardiomyocytes revealed in various parts of the heart are explained at their unequal loading under pressure.
