Cardiopulmonary exercise test (CPET) has an important role in assessing heart failure (HF) patients. Among CPET parameters, a pivotal role is attributed to the anaerobic threshold (AT), normally determined by V-slope, ventilatory equivalent and end-tidal methods. In about 10% of healthy subjects, a lack of concordance between these methods has been reported. This event was named double AT (DT). We hypothesized that DT was due to a delay in chemoreflex response.
