Key result
A 10% hemorrhage decreases late-systolic right atrial filling and absolute end-systolic volume versus baseline.
p-value: p=<0.05
In a dog model, specific components of right atrial volume (Vs and Vabs) are highly sensitive to hemorrhage and may serve as indexes of atrial B fiber activity.
No takes yet. Share an insight, caveat, or question.
May index atrial B-receptor activity in experimental hemorrhage; leaves open human validation and clinical translation.
Carlson et al. (1986) studied Hemorrhage (n=10). Hemorrhage vs. Base line was evaluated on Atrial volume components (filling during late ventricular systole [Vs] and absolute volume at end of ventricular systole [Vabs]) (p=<0.05). Hemorrhage of 10% significantly decreased atrial filling during late ventricular systole and absolute volume at the end of ventricular systole compared to baseline (P<0.05).
