Key result
Spontaneous baroreflex sequences occur at about one-third the frequency of breathing, with their onset timing dictated by the phase of respiration.

Respiratory phase should be considered when analyzing baroreflex sequences; leaves open relevance in cardiovascular disease.
Observational (n=10)
Spontaneous baroreflex sequences are not uniformly distributed but are deterministically linked to the respiratory cycle, reflecting respiratory gating of muscle sympathetic bursts.
Rothlisberger et al. (2003) conducted an observational in Healthy (n=10). Breathing phase vs. Apnea was evaluated on Timing and gain of spontaneous baroreflex sequences relative to respiration phase. Spontaneous baroreflex sequences occur at about one-third the frequency of breathing, with their onset timing dictated by the phase of respiration.
