In 1974 we introduced the treadmill exercise sub-pole load test and double the two ladder exercise test results that the double step ladder test less sensitive than the treadmill test, the positive rate of coronary heart disease detected at the census In addition, the results of the two kinds of proofreading sometimes do not match well. Therefore, it is necessary to make a new evaluation on some positive standards of double second-step exercise. To this end, on the basis of the original accumulated 341 treadmill and secondary ladder test, are analyzed as follows:
