Isometric relaxation in rat myocardium: load dependence and influence of caffeine.

C Poggesi, L Ricciardi, C Reggiani, R Minelli.   

Abstract

When caffeine plus calcium is added to the perfusing medium, isometric relaxation of rat myocardium is no longer affected by length changes occurring during the twitch. The dependence of isometric relaxation on the initial muscle length is still present and more pronounced after caffeine addition.
