Activation of the vestibular-sympathetic reflex reduces cardiac workload despite peripheral vasoconstriction, likely due to reduced pressure from wave reflections and reservoir pressure.
Does activation of the vestibular sympathetic reflex with head-down rotation affect cardiac workload in healthy young adults?
Activation of the vestibular-sympathetic reflex via head-down rotation reduces cardiac workload in healthy young adults by decreasing wave reflection and reservoir pressure.
Despite peripheral vasoconstriction, activation of the vestibular-sympathetic reflex results in a reduction in cardiac workload. Reduction in cardiac workload is likely due to reductions in pressure from wave reflections and reservoir pressure.
Pascual et al. (2023) studied this question. Activation of the vestibular-sympathetic reflex reduces cardiac workload despite peripheral vasoconstriction, likely due to reduced pressure from wave reflections and reservoir pressure.
