About 40 investigators in this special field of investigation took part in this conference. Although the group included nearly all those who are doing research on electrokymography, it was small enough to permit free and detailed discussion of each paper. The various technical aspects of this procedure, as well as the clinical application, were covered well in the papers and discussion that followed.
Electrokymography was developed jointly by members of the staff of Temple University Medical School and the United States Public Health Service. The first electrokymograph made its appearance in 1945. The instrument today is essentially a photoelectric device by which the movements of the heart, as they appear on a fluoroscopic screen, are recorded. The heart border movements and changes in density of the cardiac shadow are translated by the electrokymograph to current changes, which, by means of a beam-type galvanometer, can be made to record on moving
