Caffeine contracture in frog cardiac muscle after exposure to high concentrations of calcium

The Japanese Journal of Physiology

Abstract

Caffeine induced contracture in frog auricular muscle at room temperature when the muscle was exposed to a Ca-rich solution. The initial transient tension lasted 10-30 sec, and it was inhibited by procaine. It was dependent on caffeine concentration and the time of exposure to a Ca-rich solution prior to caffeine attack, but was little dependent on Ca concentration during caffeine contracture.
