Don't take your heart for granted

The program opens with the TV Guide citation and medal awarded to The Johns Hopkins Science Review, the first university program on the air, for its outstanding educational programming. Mortimer Loewi, Director of the DuMont Network; Kenneth Carter, general station manager of WAAM; and P. Stewart Macaulay, provost of The Johns Hopkins University, express thanks to TV Guide and pay tribute to the scientists who make the shows possible. Dr. John Spence demonstrates heart percussion, developed in 1761 by L. Auenbrugger, to outline the position and shape of the heart, which can now be done by x-ray. Dr. Francis Schwentker uses a model of the heart and a water pump to demonstrate heart activity and uses diagrams of the heart to explain the route of blood circulation, which is also shown on a human model. With the use of the heart model and diagrams, Dr. Schwentker explains the problems caused by congenital heart malformations (and the blue baby operation by Drs. Taussig and Blalock to correct it), rheumatic fever, high blood pressure, and coronary heart disease. He then demonstrates how the heart functions are studied with percussion and x-ray, stethoscope, blood pressure monitoring, electrocardiogram, heart catheters, and angiograms. Finally Dr. Schwentker notes the different ways heart problems are being prevented. An ad at the end of the show encourages viewers to contribute to their local heart fund during Heart Month.
