Abstract
Tension fall of frog heart contraction was analyzed under voltage-clamp conditions. It appears mostly exponential. The rate of relaxation depends upon the extracellular and intracellular Na concentrations. This suggests that the relaxation is under the control of Na-Ca exchange. The speeding up of relaxation by adrenaline in frog heart is revealed by low Na solution, while it is hidden by the primordial Na-Ca exchange in Ringer's solution.
