Abstract
In another communication,1a method was described for measuring the excess oxygen consumption during exercise, the oxygen debt and the time required for recovery. It was found that these measurements, particularly the excess oxygen consumption during exercise, were greater than normal in patients with organic heart disease and a history of some limitation of activity, even when no congestive heart failure was present. It was concluded that this test yields a useful objective quantitation of the cardiac capacity. The method previously described involved the use of an extension arm on the usual Roth-Benedict basal metabolism machine, and the calculation of results from multiple slopes recorded on a long paper record made by pasting three of the standard basal metabolism sheets end to end. In the present communication we are describing a simplified method which, in addition to other advantages, facilitates the calculation of results. METHOD The present method differs
