Frederic L. Eldridge,

Heart Rate Variability and Autonomic Control

The respiratory control system at a conceptual level includes a set of receptors, some of which are chemoreceptors, which gather information about their environment and a complex array of neural connections which processes and sends the information to a set of effectors, the muscles, which produce ventilation. Although in the past most attention has been paid by respiratory physiologists to the chemoreceptor influences, it should be apparent that the neural elements of the system are crucial to its understanding. In this brief presentation, not even a superficial coverage can be made of all aspects of the system. Therefore, I have taken the liberty of selecting some topics which I believe are potentially important in the overall control of breathing, especially during conditions such as exercise or when a chemical stimulant is given.
