Does incremental intravenous inotropic stimulation compare to maximal bicycle ergometry in assessing cardiac pumping capability in patients with moderately severe heart failure?
Inotropic challenge is an effective alternative to exercise testing for assessing cardiac pumping capability in patients with heart failure, particularly useful for those unable to exercise.
Tan et al. (1989) studied this question.
