Key result
Spontaneous brief elevations of arterial pressure provoked highly linear increases in R-R intervals, with slopes averaging 12.4 +/- 2.2 ms/mmHg and correlation coefficients of 0.81 +/- 0.09.

Do spontaneous brief elevations of arterial pressure provoke linear increases in heart period (R-R interval) in resting human volunteers?
Effect estimate: Slope 12.4 +/- 2.2 ms/mmHg
Spontaneous elevations in arterial pressure trigger highly linear increases in efferent vagal-cardiac nerve activity with a one heart-beat latency, demonstrating intact baroreflex physiology in resting humans.
Fritsch et al. (1986) reported an observational. Spontaneous brief elevations of arterial pressure was evaluated on R-R interval changes related to preceding systolic pressures (Slope 12.4 +/- 2.2 ms/mmHg). Spontaneous brief elevations of arterial pressure provoked highly linear increases in R-R intervals, with slopes averaging 12.4 +/- 2.2 ms/mmHg and correlation coefficients of 0.81 +/- 0.09.
