In response to changes in metabolic demand, the cardiovascular and respiratory systems
are regulated in a highly coordinated fashion, such that both ventilation and cardiac output …

Cardiac vagal withdrawal when moving from supine to an upright posture may be
independent of respiratory sinus arrhythmia. Further, ventilatory efficiency of an upright lung …

Cardioventilatory coupling (CVC) is a temporal alignment between the heartbeat and
inspiratory activity caused by pulsatile baroreceptor afferent activity. However, although first …

The circulatory system is strongly coupled with the respiratory system in human body, which
can be measured by the heart rate and respiratory signals. We construct a new metric called …

" Is there no cause for primary, or spontaneous variability [in natural selection]? Is it not
presumed under the law of inheritance that, in order that the offspring may be the exact type …

Background Spectral analysis of the cardiac time series has been used as a tool for
assessing levels of parasympathetic and sympathetic modulation of the sinoatrial node. In …

Two decades of researches showed a linear relationship between heart rate variability
(HRV) and emotion regulation, health and disease. HRV reduction was associated with …

In this paper I endeavored to show that respiratory sinus arrhythmia closely corresponds
with the perception of psychosomatic complaints. To achieve this aim, two groups of …

Sirkulasjon og respirasjon er i et viktig samspill. Dette samspillet er avgjørende for kontrollen
av det kardiovaskulære systemet. De sirkulatoriske og respiratoriske variablene inneholder …

Background There is a vast variety of oscillations within the cardiorespiratory system. One of
the most studied oscillations is heart rate variability (HRV) in the high-frequency interval …
