Abstract
It is shown that moderate low and superlow temperatures as well as general overheating of the organism cause a marked decrease in the total volume of mitochondria and sarcoplasmic matrix in cardiomyocytes of the left ventricle. These alterations develop in all cases and do not depend on changes (an increase or decrease) in the heart mass. The most pronounced alterations in the total volume and area of the main organelles of cardiomyocytes are noted after general cooling of the organism.
