HMM?? Not sure, but i would say this shows we do not bounce back as quickly as healthy. But then the CHF pts are worse. Oxygen kinetics during 6-minute walk tests in patients with cardiovascular and pulmonary disease. BMC Pulm Med. 2014; 14:167 (ISSN: 1471-2466) Kern L; Condrau S; Baty F; Wiegand J; van Gestel AJ; Azzola A; Tamm M; Brutsche M BACKGROUND: The 6-Minute Walk Test (6MWT) is representative of daily-life activities and reflects the functional capacity of patients. The change of oxygen uptake (VO2) in the initial phase of low-intensity exercise (VO2 kinetics) can be used to assess submaximal exercise performance of patients.The objective of the following study was to analyse VO2 kinetics in patients with different pulmonary and cardiovascular diseases. In addition, we investigated the extent to which VO2 kinetics at the onset of the 6MWT were associated with exercise capacity, morbidity and mortality. METHODS: VO2 kinetics of 204 patients and 16 healthy controls were obtained using mobile telemetric cardiopulmonary monitoring during a 6MWT. A new mean response time (MRT) index (wMRT) was developed to quantify VO2 kinetics by correcting MRT for work rate. The differences in wMRT between disease categories as well as the association between wMRT and patients exercise capacity and outcome - time to hospitalization/death- were tested. RESULTS: The assessment of a robust wMRT was feasible in 86% (244/284) patients. wMRT was increased in patients compared to healthy controls (p
