Examine the action of digoxin as a therapy for heart murmurs.
Carotid Sinus Massage is used as a clinical tool in the diagnosis of certain cardiovascular disorders. In addition, it’s simply a cool bit of physiology that highlights part of the baroreceptor reflex.
In simple terms, what effect(s) do/does the manual massaging of the carotid sinus have on the above-noted effector(s)? Why?
It is thought that the elderly tend to have hypersensitivity with this reflex; often contributing to death. It’s also believed that this response partially contributes to death by hanging or by manual strangulation. Briefly describe how this too is consistent with your understanding of the reflex.
