Motion-Picture Techniques for Teaching Heart Sounds and Murmurs

The production of a motion picture to teach the diagnosis of a common congenital heart defect correctable by surgery required the clear demonstration of certain heart sounds and murmurs. Butterworth has shown that learning the difficult skill of cardiac auscultation is facilitated by bringing the student's eyes to the aid of his ears through use of an oscilloscope coupled with a sound amplifier connected to stethoscopes. The motion-picture medium, with its manipulatability of picture and sound, offered an opportunity to improve upon the efficiency of this teaching method. Problems inherent in the subject and the limitations of reproduction with 16mm optical sound are presented and solutions described.
