自从1866年,Czermack首次介绍压迫颈动脉引起心率下降以来,医务界已经认识到颈动脉窦对生命的影响。后来,Herring叙述了这个部位的解剖,发现不是由于压迫神经本身引起心率下降,而是由于压迫了颈动脉分叉处的伸经末梢。直到1933年,Weiss和Baker才首先叙述了颈动脉窦过敏综合征。颈动脉窦的压力感受器位于颈动脉分叉处的外膜内。压力冲动由此传入沿颈动脉间神经走行的有髓传入神经纤维,与舌咽伸经相连接,然后传入网状髓质,并由此发出对心血
Since Czermack first introduced the reduction of heart rate caused by compression of the carotid artery in 1866, the medical community has recognized the impact of carotid sinus on life. Later, Herring described the anatomy of this area and found that it was not due to compression of the nerve itself that caused the heart rate to fall, but because of compression of the distal end of the carotid bifurcation. It was not until 1933 that Weiss and Baker first described the carotid sinus hypersensitivity syndrome. The carotid sinus baroreceptors are located in the adventitia of the carotid bifurcation. The pressure impulse is transmitted to the myelinated afferent nerve fibers that travel along the inter-carotid nerve and is connected to the glossopharyngeal extension and then to the reticular medulla.
