Abstract

Summary: Changes in external pH from 7.40 to 6.95 obtained by changing the pCO₂ of the medium at constant bicarbonate concentration produced in cat papillary muscles a significant decrease in isometric tension with no changes in time to peak tension. Active and resting stiffness, as determined by two different methods, did not change under conditions of hypercapnic acidosis.
