Key result
Complete autonomic blockade significantly reduced the number of nonbaroreflex sequences compared to baseline (19.1 vs 88.7, P<0.05), as did sympathetic and parasympathetic blockades.
Absolute Event Rate: 19.1% vs 88.7%
p-value: p=<0.05
Nonbaroreflex sequences in spontaneous arterial pressure and heart rate fluctuations appear to represent an integrated, neurally mediated feed-forward mechanism of short-term cardiovascular regulation.
No takes yet. Share an insight, caveat, or question.
Nonbaroreflex sequences may reflect neurally mediated feed-forward control in animals; leaves open their role in human BP regulation.
Legramante et al. (1999) studied Anesthetized rabbits (n=64). Autonomic blockade vs. Baseline (before blockade) was evaluated on Number of nonbaroreflex sequences (p=<0.05). Complete autonomic blockade significantly reduced the number of nonbaroreflex sequences compared to baseline (19.1 vs 88.7, P<0.05), as did sympathetic and parasympathetic blockades.
