-Monophasic action potentials which were obtained by suction electrode from toad ventricle did not show change in its amplitude with varying temperature. But the integral of a monophasic action potential decreased hyperbolically with rising temperature and the integral per minute, the area obtained by multiplying a single area with pulse rate, increased linearly with temperature. The relationship to temperature of mechanical work of the ventricle contraction and its work per minute was the same as in the case of the integral of action potential. That is to say, there was found a linear relationship between the work per minute and the integral of the action potential per minute. These observations suggest that, for the coupling of the mechanical work and the electrical phenomena of the heart, electrostatic treatments are needed.
