title: [Morphometric research on the cardiomyocytes in cardiac hyperfunction].
abstract: By means of a complex morphometrical method special quantitative parameters of cardiomyocytes have been studied in the cardiac parts of 37 dogs, 6 months after right-sided pulmonectomy, and of 12 control dogs. The cardiac hyperfunction is accompanied with an increased mass of the heart's parts, hypertrophy of the right ventricle and right atrium dominating. Hypertrophy of myocardial parts takes place mainly at the expense of the increasing length and width of cardiomyocytes. This causes disorganization and disorder of morphological systems and an essential decrease in compensatory possibilities of the hyperfunctioning heart parts.
