Baroreflex Correction of Blood Pressure

A blood-pressure step is corrected by an opposite heart-rate change with the cited sensitivity -1 bpm/mmHg and latency 0.68 s; the response is linear over ±20 mmHg and the closed loop regulates pressure back to its setpoint with heart rate at the cited resting 70 bpm. Gain/latency grade [L].

Rate-level baroreflex: -1 bpm/mmHg (correct sign), latency 0.68 s, linear over ±20 mmHg, closed-loop regulation to 70 bpm. [L].

A pressure step is corrected by a rate change

The baroreflex is modeled at the rate level, because a relaxation oscillator's cycle rate is correctly insensitive to its drive — the autonomic loop must set the SA-node operating rate, not its FHN drive. A blood-pressure disturbance drives a compensating heart-rate command with cited gain and latency.

The static sensitivity is -1 bpm/mmHg with the correct sign (a pressure rise lowers heart rate), matching the cited baroreflex sensitivity. The onset latency is 0.68 s, at the cited value.

Linear over the tested range; regulates to setpoint

The response is linear in the pressure step over ±20 mmHg, and the closed loop returns pressure to its setpoint, with heart rate settling at the cited resting value 70 bpm.

Grade

Gain and latency are anchored to cited baroreflex values, so this target is grade [L]; the verified content is the correct sign, linearity, and closed-loop regulation to the cited setpoint.
