Where are the sympathetics for CV?
T1-6
Where do these sympathetics synapse?
- upper thoracics
2. Cervical chain ganglia
sympathetics from right pass and right deep plexus innervate?
SA node
Hyperactivity of R. deep plexus/pass predisposes to?
Suprventricular Tachy
L pass through L. deep plexus innervate?
AV node
Hyperstim of L-pass/plexus =>?
Ectopic foci
V. Fib
Increased tone assc. w/increased ____ post MI.
Morbidity
Increased tone does what to collateral circulation development?
Inhibits it
Vessels rich in sympathetics =>
vasoconstriction
What nerve goes to the SA node?
Right Vagus N.
Hyperactive Vagus N. =>
Sinus brady arrythmias
L. Vagus supplies?
AV node
Hyperactivity of L. Vagus leads to?
AV blocks
Visceral-visceral reflexes are pulmonary branches strongest inhibitory reflex-?
Aspiration
Parasympathetic visceral to visceral reflexes cause?
- Slowing HR
- Larynx irritation
- Pressure on carotid and globe of eye
Visceral-visceral reflexes are less affective in ____ pts and more affective in ____ pts.
- Sympathecotonic
2. Vagotonic
Where are Vagal connections abundant?
OA, AA and C2
Drainage from heart and lungs goes where?
R. Lymphatic duct
If drainage is impaired what can happen?
Homeostatic mechanisms become impaired
-increased morbidity and mortality w/heart problems
Peripheral lymphatic congestion is linked to?
Atherosclerosis and HTN
Thoracic duct is under ____ control?
Sympathetic control
Hypersympathetic activity can do what to lymphatic flow capacity?
Reduce flow capacity
What is considered severe scoliosis and how does it relate to cardiac function
- 75 degree thoracic curve
2. Compromises cardiac function
Pts with decreased CO, irregular gait patterns increase cardiac workload how much?
300%
-work to restore gait to normal
