交感神经和副交感神经(Sympathetic and parasympathetic nerves)
Parasympathetic reflexes and sensory axon responses combine to increase nasal blood flow, fill venous sinusoids (which thickens the mucosa and reduces nasal patency), induce plasma extravasation, and stimulate glandular secretion of mucous and serous cell products. These putative roles for nerves and ...

The SD1 is related to fast beat-to-beat variability whereas SD2 is linked to long-term RR interval variability and is influenced by both sympathetic and parasympathetic components. Indexes of parasympathetic function are thought to be rMSSD, SDRR, pNN50% and HF fluctuations in heart rate (in ...

Time domain HRV parameters of the three groups revealed a higher degree of sympathetic activation in the lower quartile (reverse dipper) vs. the upper quartile (extreme) and normotensive controls. HRV parameters related to parasympathetic tone did not show any significant variations among the three ...
