To examine the reproducibility of cardiopulmonary exercise testing in patients with heart failure, three consecutive tests were performed in 30 such patients. The first test underestimated treadmill exercise time by about 20% when compared with the second and third tests, which were not significantly different. Peak achieved VO2, VCO2 and VE were also less during the first test, but blood pressure, heart rate and respiratory rate responses were similar in the three tests. When cardiopulmonary exercise tests are used to assess functional capacity in either individual patients or groups (as in a therapeutic trial), at least two tests should be performed, as a single test is likely to underestimate exercise capacity.
为了检验心力衰竭患者心肺运动试验的可重复性，对30例此类患者进行了连续三次测试。与第二次和第三次测试相比，第一次测试低估了跑步机运动时间约20%，而后两次测试无显著差异。第一次测试时达到的峰值摄氧量、二氧化碳排出量和分钟通气量也较低，但三次测试中的血压、心率和呼吸频率反应相似。当使用心肺运动试验评估个体患者或群体（如在治疗试验中）的功能能力时，应至少进行两次测试，因为单次测试可能会低估运动能力。
