Key result
Falling pressure yielded a rightward shifted and more sensitive arterial baroreflex response curve compared to rising pressure, causing a hysteresis reversal at hypotensive pressures.
Observational
The arterial baroreflex exhibits hysteresis, processing diastolic pressure differently depending on whether pressure is rising or falling.
No takes yet. Share an insight, caveat, or question.
Baroreflex hysteresis reversal at hypotension warrants no practice change; leaves open its relevance to human BP control and modeling.
Incognito et al. (2020) reported an observational. Falling pressure vs. Rising pressure was evaluated on Arterial baroreflex response. Falling pressure yielded a rightward shifted and more sensitive arterial baroreflex response curve compared to rising pressure, causing a hysteresis reversal at hypotensive pressures.
