This study examined whether the sympatho-inhibitory response of the heart to acupuncture-like stimulation of a hindlimb in anesthetized rats depends on the sympathetic tone. Observed reductions in both cardiac sympathetic nerve activity and heart rate following short-term acupuncture-like stimulation of a hindlimb were not augmented when the sympathetic tone was high as a result of hypercapnia.
本研究旨在探讨麻醉大鼠后肢类似针刺刺激引起的心脏交感抑制反应是否依赖于交感神经张力。观察到的短期后肢类似针刺刺激引起的心脏交感神经活动和心率降低,在高碳酸血症导致交感神经张力增加时并未增强。
