摘要

By means of the echocardiographic techniques, morphometric and functional parameters of the heart left ventricle (HLV) were studied in male humans aged 20 to 23, in resting and under the effect of a physical load. The total ventricle work was found to be about 1 J, the relative one (per 100 g of the LV mass)--0.6 J. The total working power was found to be about 70 Watt, the relative one--about 40 Watt. The physical load resulted in increase of the LV mechanical work parameters due to the heart rate and systolic arterial pressure.
