A fundamental and clinical study on treadmill exercise testing

The treadmill test developed in the USA has been widely used to diagnose angina pectoris related to exertion. But there are some problems, such as overload, when this test is applied to Japanese, since it has been designed for Occidentals. Therefore, in this study the treadmill test was modified for Japanese, and its validity was compared with Master's two step test. Furthermore, the optimum maximum heart rate of healthy Japanese, as one of the most important criteria for treadmill test, was evaluated, and the influence of age on this criterion was investigated. The relationship between the end point heart rate of the patients with angina pectoris and age was also studied. For the results, (1) The positive rate of the treadmill test on angina pectoris was significantly higher than Master's test (84.6% vs 50%, p
