1. Measurements have been made of tension development in papillary muscles isolated from the right ventricles of young cats. In some cases membrane potentials have also been recorded, using micro electrodes. 2. Regular contractions at a stimulation rate of 20 min(-1) (the 'standard' rate used in this study) had the following characteristics (30 degrees C): peak tension developed, about 43mN mm(-2); time to peak tension and time to 80% repolarization of the cell membrane, about 400 ms. 3.
