[Effect of hypokinesia on the contractile function of the myocardium]. | Rats were subjected to hypokinesia for two months and the contractile function of isolated papillary muscles was studied. Hypokinesia reduced significantly the isotonic contraction velocity which depended on the ATPase activity of the myofibrils; it also reduced the velocity and index of relaxation which depended on th... | 423,440 | [
