ABSTRACT
The effects of external Na+ concentration and stimulation rate changes on the post rest contraction of rat myocardium were studied. An increase in external Na+ concentration or in stimulation rate causes relative potentiation of the post rest contractions, suggesting that the sarcolemmal Na+-Ca2+ exchange mechanism affects the mafgnitude of the potentiation of post rest contractions
