运动试验已广泛应用于临床心脏心脏病学中,如诊断心脏病,估价其病情的严重程度和预后,确定病员许可运动量大小和判断内外科冶疗的效果等。动力型腿部运动试验的二级梯,活动平板和踏车运动试验都经常应用于此目的,为了某些特殊的目的也可作手臂肌等长运动试验,因此,在临床实践中常常要比铰不同仪器所作运动试验的结果。为了资料能够相比较,必须定出工作负荷的强度,通常用每分钟最大氧耗重(VO_2)这一术语表示之。心脏科医师的注意力主要在于运动付的负荷对心脏所造成的影响,如运动时循环系统的反应,过去已有报导,在同样VO_2的情况下,运动时的循环反应是不同的,取决于所涉及的肌组(臂或腿)、运动的形式(动力型或等长型)、体位(站位、坐位或臥位)、环境条件
Exercise tests have been widely used in clinical cardiology, such as the diagnosis of heart disease, assess the severity of the disease and prognosis, to determine the size of patients allow exercise and determine the effect of surgical treatment. Dynamic leg movement test of the second ladder, treadmill and treadmill exercise tests are often used for this purpose, for some special purposes can also be used for arm muscle isometric exercise test, therefore, in clinical practice often than The results of the exercise test performed by different instruments. In order to be able to compare data, the strength of the workload must be set, usually expressed in terms of maximum oxygen consumption per minute (VO_2). The attention of cardiologists mainly depends on the effects of exercise-induced stress on the heart, such as the circulatory response during exercise. It has been reported in the past that in the case of VO_2, the circulatory response during exercise is different depending on The muscles involved (arms or legs), the form of exercise (dynamic or isometric), body position (station, sitting or lying position), environmental conditions
