Association between RR interval and high-frequency heart rate variability acquired during short-term, resting recordings with free and paced breathing.
High-frequency (HF) oscillations in RR interval from 0.15-0.40 Hz are widely accepted as a measure of cardiac vagal outflow but the HF/RR relationship appears complex, particularly with longer RR intervals. The aim of this study was to evaluate the HF/RR interval relationship during free and paced b...
