The physiological importance of respiratory sinus arrhythmia (RSA) and cardioventilatory coupling (CVC) has not yet been fully elucidated, but these phenomena might contribute to improve ventilation perfusion matching, with beneficial effects on gas exchange. Furthermore, decreased RSA amplitude has...
