台阶试验是运动负荷试验的一种形式，用于判断人体的心血管功能，在国际上应用比较广泛。虽然台阶试验对于测试心血管系统功能是一个比较理想的指标，但由于相对费时，且测脉搏又比较繁琐，因此，在我国应用不多。近年来，随着我国经济与社会的发展，进行大面积台阶试验的可能 Step test is a form of exercise stress test. It is used to determine the cardiovascular function of the human body and is widely used in the world. Although the step test is an ideal indicator for testing the function of the cardiovascular system, it is relatively time-consuming and the pulse measurement is more complicated. Therefore, it is not widely used in China. In recent years, with the development of China’s economy and society, it is possible to conduct large-scale step tests.
