Abstract
• Motion pictures of the heart as it appears in fluoroscopy can be made by using a camera in connection with an image-intensifying tube. The pictures can be greatly slowed for study by various means, so that the events of one second take almost 14 seconds to view on the screen. Detailed analysis of the movements of the heart shadow can be made with reference to other aspects of cardiac function, since the electrocardiogram, ballistocardiogram, phonocardiogram, or any other record transmissible to an oscilloscope, can be photographed in synchronism with the heart shadow.Keywords
