Exercise oscillatory ventilation (EOV) is a phenomenon characterized by cyclic oscillations in the ventilatory pattern observed during the cardiopulmonary exercise test. It is considered an independent predictor for death and adverse cardiovascular events in chronic heart failure (CHF) patients. A recent meta-analysis showed that EOV-positive patients exhibited a worse peak oxygen uptake (VO2PEAK) and ventilatory efficiency (VE/VCO2 slope). Although the EOV pathophysiology is not fully understood, current evidence suggests that circulatory delay, pulmonary congestion, high chemosensitivity, and exacerbated ergoreflex signalling are the main triggering factors.
