Abstract

It has been shown that a relatively constant amount of work under standard conditions induces attacks of angina pectoris in a given patient. It is possible, therefore, to study the influence of various agents on this condition.1,2,3 The present communication describes the effect of breathing high concentrations of oxygen on the amount of work which patients with angina pectoris can do before developing pain.
