“… 7 The carotid sinus is a dilated neurovascular structure at the junction of the internal and external carotid artery, which is enriched with baroreceptors; increased pressure in these sinuses can be sensed by afferent glossopharyngeal nerve fibers which transmit signals to nucleus solitarius and outflow of parasympathetic fibers, thereby cause bradycardia and/or hypotension. 8 Like DS, CSH is also common in the elderly population. 2 , 8 Part of the reason it is more common in the elderly could be attributed to the degeneration of autonomic nuclei in the medulla oblongata and overt responses.…”

“… 8 Like DS, CSH is also common in the elderly population. 2 , 8 Part of the reason it is more common in the elderly could be attributed to the degeneration of autonomic nuclei in the medulla oblongata and overt responses. 9 To date, literature mentions 3 varieties of CSH: cardioinhibitory type: leading to a decrease in heart rate, asystole, and heart blocks.…”

“…Asystole should be above 3 seconds, but systolic blood pressure should not drop more than 50 mm Hg, vasodepressor type: isolated systolic blood pressure drops of more than 50 mm Hg, and mixed: having mixed manifestation of both cardioinhibitory and vasodepressor type. 8 …”
