The differential diagnosis of precordial pain may present a difficult problem. It is for this reason that the electrocardiogram has recently gained such wide vogue. However, it is now apparent that a normal electrocardiogram does not necessarily exclude coronary disease and it is becoming clearer that other diseases can lead to electrocardiographic changes which may imitate coronary patterns. A need has developed for some tests to measure the adequacy of the coronary circulation. Two such tests are now being used. One is the anoxemia test, the other the exercise test. In both the judgment is based upon the electrocardiographic alteration.
