> inspiration increases intrathoracic pressure which triggers the CV control mechanism to think BP is higher via the baroreflex and therefore lower HR It seems CRC raises HR during inspiration. From https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4052709/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4052709/ "The increase in HR during inspiration is referred to as respiratory sinus arrhythmia (RSA) and the increase in BP as Traube–Hering waves."
