Abstract

Background: Exercise oscillatory ventilation (EOV) occurs in a sub-group of patients with increased heart failure (HF) severity and poorer prognosis. The purpose of this investigation was to examine the prognostic value of the largest ventilatory oscillation characteristics in HF patients. Methods: One hundred fifty-four subjects diagnosed with HF underwent cardiopulmonary exercise testing. Subjects with EOV were then divided into two sub-groups: (1) largest ventilatory oscillation during the first half of exercise with an oscillation width ≥30 seconds; and (2) largest ventilatory oscillation during the second half of exercise or an oscillation width
