Evaluating the physiological significance of respiratory sinus arrhythmia: looking beyond ventilation–perfusion efficiency

We conducted a theoretical study of the physiological significance of respiratory sinus arrhythmia (RSA), a phenomenon used as an index of cardiac vagal tone and wellbeing, whereby the heart rate (HR) increases during inspiration and decreases during expiration. We first tested the hypothesis that R...
