    Instability of ventilatory control is common in patients with heart failure (HF), and can manifest as osillatory ventilation. This is observed during the cardiopulmonary exercise test (CPET), and is charactenzed by a waxing and waning pattern of tidal volume (VT), without and interposed period of apnea. We describe the results of six patients diagnosed with dilated cardiopathy and heart failure, with an ejection fraction of the left ventricle between 20% and 25%, who were referred by the Heart Failure Clinic to the Pulmonary Physiology Laboratory of the Pulmonology Unit of Hospital Universitario San Ignacio for CPET as part of pre-transplant workup.
