Sandhouse - Cardiovascular Flashcards
The sympathetic nervous system effects all of the following except: (more than one may apply)
a) Heart
b) Peripheral blood vessels
c) SA Node
d) AV Node
e) Kidney and Adrenals
c) SA Node
d) AV Node
SA and AV node is innervated by the Vagus Nerve (which is PARASYMPATHETIC!)
What viscerosomatic levels is the heart at?
T1-T6
What viscerosomatic levels are peripheral blood vessels at?
T1-L2
What viscerosomatic levels are the kidneys and adrenals at?
T10-L2
Which is not a role of the sympathetic nervous system:
a) Maintain vascular tone
b) Decrease heart rate and contractility
c) Increase Cardiac Output
d) Vasoconstriction
b) Decrease heart rate and contractility
T or F: The right vagus innervates the AV node.
FALSE; The RIGHT vagus innervates the SA node; the LEFT vagus innervates the AV node
Lymphatic drainage from the heart predominately goes to the left or right lymphatic duct?
Right lymphatic duct
Which of the following can impaired lymphatic drainage result in? (name all that apply)
a) increased morbidity and mortality from ischemia and infection
b) atherosclerosis
c) development of HTN
d) Pulmonary edema, ascites, hepatomegaly and peripheral edema
e) increased morbidity in patients with CHF due to electrolyte imbalances
f) decreased collateral circulation
ALL OF THEM!
a) increased morbidity and mortality from ischemia and infection
b) atherosclerosis
c) development of HTN
d) Pulmonary edema, ascites, hepatomegaly and peripheral edema
e) increased morbidity in patients with CHF due to electrolyte imbalances
f) decreased collateral circulation
What If you feel hypersympathetic activity on the right side, what could this mean?
SVTs
What If you feel hypersympathetic activity on the left side, what could this mean?
ectopic foci, VF
What If you feel increased sympathetic tone via somatovisceral changes, what could this mean?
coronary vasospasm
A patient presents with vascular and cardiac hyperreactivity to sympathetic stimuli, what disease could they have?
Essential HTN
If a patient has prolonged sympathetic stimuli to the kidneys, what could this cause?
Elevated BP due to functional retention of water and salt
A patient shows hyperparasympathetic activity on the right side, what the heck is going on?
sinus bradyarrythmias
A patient shows hyperparasympathetic activity on the left side, what the heck is going on?
AV blocks
