| Abstrakt: |
A comparison was conducted between the contractile function of the heart of hares and rabbits at rest and under isometric contractions regimens, and under such conditions the concentration of ATP and its breakdown products was studied in the myocardium of both species. It was demonstrated that the cardiac muscle of hares adapted by the evolution to the performance of intensive work does not possess any increased ability of developing systolic tensions, or any increased power of the ATP resynthesis apparatus. The advantage of such a heart-- its ability to pump an increased blood volume -- must be ensured by some different mechanism that requires still further investigations. |
