The electrokymograph is an instrument which permits the graphic registration of the movements of the heart and great vessels. Many investigators of the cardiodynamics of health and disease have pointed out the importance of studying these movements. Beginning with observations made by the physiologists on the exposed heart, an increasing fund of knowledge has been accumulated. Fluoroscopy, roentgencinematography,1 and roentgenkymography2, 3, 4 have all contributed basic information. Each method has definite limitations and only fluoroscopy has wide clinical usage. There is need for methods which can be more easily applied to physiological and clinical usage in intact subjects.
