[Comparative diagnostic value of the isoproterenol test and the exercise test in detection of coronary insufficiency]
Abstract
It appears that a constant-speed infusion of isoproterinol is as reliable and sensitive a method of detecting coronary insufficiency as the exercise test. It is indicated when: - the exercise test is impossible or not submaximal; - there is disagreement between the clinical findings, which are suggestive, and ergometry, which is negative; - there is pure angina of effort arising spontaneously.
