In order to study the relation of venous-return to cardiac action, right auricular volume wave and electrocardiogram were simultaneously recorded. For this purpose, special-condenser-microphone, which was connected to Koizumi-Okada-takasaki's electricvolumetric sphygmocardiograph, was introduced through the neck vein till it reached the right auricle of dog used in this experiment. After seeing the relation of cardiac cycle to the right auricular wave, the part of the wave which was recorded in the systolic ejection phase of ventricle, was studied espicially in full detail. It was made clear that this part of the wave showed nothing but the rapid volume increase of the auricular blood volume. We assume that venous return is accelerated simultaneous with cardiac ejection. This fact gives an experimental verification to Pr. Maekawa's theory about the mechanism of heart to venous return - he proclaimed that heart acts like suction pump in systolic ejection phase. This is the reason why I call this part of the wave rSm wave (Maekawa's right auricular suction wave).
