title: Transient fall in oxygen intake during exercise in congestive heart failure.
abstract: We report four cases in which oxygen intake abruptly decreased during a graded exercise test. In all these cases, there was an acute event (arrhythmia, mitral regurgitation) that had very likely resulted in a decrease in cardiac output. These studies provide new evidence of oxygen intake dependence on oxygen transport, even in nonsteady-state situations.
