WebHeart rate (HR) increased during inspiration, with a nearly fixed time delay for most VT and BF approximating 0.9 s. The magnitude of RSA increased with increases in VT and with decreases in BF. SBP decreased during inspiration, with a time delay which increased as BF decreased, resulting in a phase delay approximating 160 degrees.
