Force-velocity relation for the tetanic contraction of frog atrial muscle.
The hyperbolic force-velocity relation was obtained by afterload method for the tetanic contraction of frog atrial muscle. The dynamic constants (a/Fm and b), the maximum velocity and especially the maximum tension were considerably smaller than those of ventricular muscle.
