当连续的超声波从胸壁表面向心脏发出时，心脏运动会对从其反射的分波产生多普勒效应。因此，适当构造用于发送和接收超声波的装置对于研究心房、心室或瓣膜等的运动是非常有用的，通过分析各部分运动产生的特殊多普勒信号，作者开发了一种通过与心电图机和心音图机同时记录这些多普勒信号来检查心脏功能的方法。这种方法不仅可以获得迄今为止尚不能确定的瓣膜运动的直接信息，而且可以检查单独用心电图机完全无法检测到的心肌兴奋的过渡方面。
When the continuous ultrasonic wave is sent forth towards the heart from the surface of the chest wall, the cardiac motion causes the Doppler effect upon the partial wave reflected from it. Therefore, an apparatus suitably constructed for sending and receiving ultrasounds is quite useful for the investigation of the movements of theatrium, ventricle, or valves, etc., through the analysis of the particular Doppler signals developed from the motion of the respective part.The author developed a method for the inspection of cardiac functions by recording these Doppler signals simultaneously with the electro‐ and phonocardiographs the oscillograph paper. This method made it possible not only to obtain direct informations for the valvular movement which could not have been ascertained up to present, but also to examine the transitional aspects of the myocardial excitation which is utterly uudetectable by the electrocardiograph alone.
