在慢性心力衰竭患者中，最大摄氧量（VO 2 max）的测量被广泛用于评估功能能力、预后和对治疗的反应。这项调查涉及使用静态运动机与呼吸气体的在线分析。该测试可能会使患者感到困惑和不舒服;气体分析设备的购买和维护费用昂贵，并且需要训练有素的工作人员。运动员的运动测试，基于定时穿梭跑，来回超过20米的课程与VO 2最大值的测量。1 Singh等人开发了一种10 m穿梭行走试验（SWT），用于评估慢性气道疾病2和永久性起搏器植入患者。3两个圆锥体相距9 m，患者在圆锥体外来回走动。盒式磁带录音给病人指示，并通过一系列哔哔声控制测试的进展。患者需要行走，以便在每次哔哔声响起时完成一个转弯。该测试是渐进的和最大的。步行速度在持续1分钟的阶段内增加，当患者未能保持所需的步速时，测试终止。记录完成的穿梭次数。我们评估了SWT在慢性心力衰竭患者中的安全性和可接受性，并检查了SWT性能与VO 2 max之间的关系。该方案得到了当地伦理委员会的批准，所有患者都签署了知情同意书。从布朗普顿心力衰竭诊所转介了50例确诊左心室功能不全的男性，以估计最大摄氧量。平均年龄
In patients with chronic heart failure, measurement of maximum oxygen uptake (VO2 max) is widely used to assess functional capacity, prognosis, and response to treatment. This investigation involves the use of a static-exercise machine with on-line analysis of respiratory gases. The test can be bewildering and uncomfortable for patients; the gas analysis equipment is expensive to purchase and maintain, and trained staff are required. Exercise tests in athletes, based on timed shuttle runs, to and fro over a 20 m course are associated with measurements of VO2 max. 1 Singh et al have developed a 10 m shuttle-walk test (SWT) to assess patients with chronic airways disease2 and permanent pacemaker implants. 3 Two cones are placed 9 m apart and patients walk to and fro turning outside the cones. A cassette-tape recording gives instructions to patients and controls the progress of the test with a series of bleeps. Patients are required to walk such that they complete a turn as each bleep sounds. The test is progressive and maximal. The walking speed increases over stages lasting 1 min and the test is terminated when a patient fails to maintain the required pace. The number of shuttles completed is recorded. We assessed the safety and acceptability of the SWT in patients with chronic heart failure and examined the relationship between SWT performance and VO2 max. The protocol was approved by the local ethics committee and all patients gave informed consent. 50 men with established left ventricular dysfunction were referred from the Brompton Heart Failure Clinic for estimation of VO2 max.
