[Effect of initial length on the chronoinotropism of the myocardium].
Shortening di the muscle initial length was found to enhance the postextrasystolic potentiation, the Bawditch stair and other signs of chronoinotropy. A hypothesis is advanced concerning the mechanisms underlying the effect of the cardiac muscle initial length on rhythm-dependent mechanical phenomena.
