摘要: In patients with chronic heart failure whose cardiac output response to exercise is impaired, determination of anaerobic threshold may provide a useful and objective approach grade the severity failure. such performing upright treadmill exhaustion, this study examined reproducibility mixed venous lactate concentration when test was repeated same or next day, nature after rest levels were augmented by cardiotonic agent amrinone during symptom-limited submaximal performed at either aerobic work for each patient. Findings were: 1) reproducible (p
