Abstract
THE electrocardiographic exercise test is a well established procedure in the diagnosis of coronary insufficiency. The method most widely used in America is the two-step test of Master.1 2 3 4 5 6 Master has standardized the exercise for the individual subject on the basis of sex, age and weight. One of the objections raised against the procedure was that the exercise was of short duration and did not permit the achievement of a steady state. However, the results of a recently published comparative study between the double Master two-step test and the exercise on a treadmill, which was sufficiently long to achieve the steady . . .Keywords
