EFFECTS OF CAFFEINE ON TENSION DEVELOPMENT IN DOG PAPILLARY MUSCLE UNDER VOLTAGE CLAMP

1. Effects of caffeine on tension in the dog papillary muscle were investigated using a voltage clamp with the double sucrose-gap method. 2. An S-shaped relationship between membrane potential and developed tension was obtained in Tyrode solution. An increase of the external calcium concentration pr...
