BACKGROUND The ventilatory threshold (VT) is usually determined by visual assessment of the point where the rate of elimination of carbon dioxide (VCO(2)) increases nonlinearly with respect to oxygen uptake (VO(2)) (the V-Slope method). We quantified the reliability of VT determination using data from a multicenter study in patients with heart failure. METHODS AND RESULTS The Fix-Heart Failure-5 study of cardiac contractility modulation enrolled 428 patients from 50 centers in the United… CONTINUE READING
