THE H-ION CONCENTRATION AND THE ORIGIN OF THE HEART BEAT |
|
| Authors: | Spealman C R |
| Abstract: | The rate of the frog or guinea pig heart preparation was not significantly influenced by the H-ion concentration when this was kept within limits which allowed the heart to continue beating. The theory that the H-ion concentration is intimately concerned with the origination of the heart beat is not supported by the results of this investigation. |
