Interest in the subject of everyday medical care in industry from the standpoint of cardiology was accelerated by experiences during World War II, when it was necessary to employ manpower from the 4-F category. This increased the incidence in industry of hypertension, arteriosclerosis, rheumatic heart disease, psychosomatic disorders, and other cardiac defects. To a great extent experiences with these groups proved that persons who had cardiac disorders with a limited disability could carry on very well in industry.
Now that manpower is more plentiful, the limited cardiac cripple is again coming up against the barrier that has so long stood in his way, namely, the attitude of the employer that more or less insists that an employee be on a full-duty status, using Army terminology, and that there is very little place for an employee who can do limited duty only. Correction of this fallacy rests on education of management
