Влияние возраста на эффективность механической работы папиллярной мышцы крысы

Abstract

The problem of quantitative characterization of the effectiveness of the cardiac muscle, in particular, extraction of the accurate energy values consumed by myocardium in the cardiac cycle is a real challenge for modem biomechanics. Fortunately, experiments with isolated papillary muscle allow estimation of energy consumptions. Current work describes the results of experimental study of the effectiveness of papillary muscle work in rat hearts depending on the age.
