Slow breathing practices have been adopted in the modern world across the globe due to
their claimed health benefits. This has piqued the interest of researchers and clinicians who …

Lung ventilation fluctuates widely with behavior but arterial PCO 2 remains stable. Under
normal conditions, the chemoreflexes contribute to PaCO 2 stability by producing small …

Frequency analysis of the electrocardiographic RR interval is a common method of
quantifying autonomic outflow by measuring the beat-to-beat modulation of the heart (heart …

It is well known that breathing introduces rhythmical oscillations in the heart rate and arterial
pressure levels. Sympathetic oscillations coupled to the respiratory activity have been …

The cardiorespiratory system exhibits oscillations from a range of sources. One of the most
studied oscillations is heart rate variability, which is thought to be beneficial and can serve …

Cardiorespiratory coupling is an encompassing term describing more than the well-
recognized influences of respiration on heart rate and blood pressure. Our data indicate that …

This study examines the effect of mental workload on the electrocardiogram (ECG) of
participants driving the Lane Change Task (LCT). Different levels of mental workload were …

Heart rate and blood pressure oscillate in phase with respiratory activity. A component of
these oscillations is generated centrally, with respiratory neurons entraining the activity of …

The body is, in essence, an ensemble of interacting systems with biorhythms nested at
multiple timescales. Traditionally, the focus in the study of body-brain interaction has been …

Heart rate variability (HRV) is a crucial indicator of cardiovascular health. Low HRV is
correlated with disease severity and mortality in heart failure. Heart rate increases and …
