Cards

Term
Left anterior descending
Definition
interventricular septum
both ventricles and bundle branches
apex of the heart
Term
Right coronary Artery
Definition
right posterior artery
SA/AV node
bundle of his
Term
right marginal
Definition
posterior R ventricle
diaphragmatic margin of both ventricles
Term
Right posterior descending
Definition
posterior interventricular septum
inferior left ventricle
Term
pre-load
Definition
after filling
end diastolic volume
increae stretch increase SV
Term
after-load
Definition
resistence the L vent. pushes against to empty chamber
Term
contractility
Definition
rate and intensity of heart contraction
Term
compliance
Definition
ease with which the heart recieves blood
decreased compliance higher EDP
increased compliance lower EDP
Term
parasympathetic control
Definition
vagus nerve
lowers tonic rate
ach
Term
sympathetic control
Definition
sympathetic chain
increases tonic firing
catecoimines NE ephidrines
Term
neural control with ex.
Definition
withdraw of vagus parasympathetic stim increases HR
Term
nerual control of trained person
Definition
increase invagus PS stim decreases resting HR
Term
barrow receptors
Definition
respond to changes in blood pressure
increase BP causes blood vessel stretch
lowers HR vasodialtion lowers BP
Term
Anticipatory heart rate
Definition
Before exercising your heart rate increases because norepinephrine from sympathetic system is released, as well as epinephrine from adrenal gland
Term
radius affects on flow
Definition
raise to the power of 4
decrease by 1/2 lowers flow by 16 fold
Term
local vasodialators
Definition
hypoxia
adenosine
increased temp
CO2
acidity
MG and K ions
all associated with increased muscular metabolism
Term
NE on vasomotor tone
Definition
vasoconstrictor
adrengic fibers
Term
Ach
Definition
Vasodialtion
cholinergif fibers
Term
phase of ex anticpation
Definition
increases HR
increased BP
Increase CO
increase venous Resist
due to symp outpowering
Term
phase of ex initiation
Definition
mechanical compression increase VR
increase HR
decrease TPR-vasodialation
increase CO
increase SV
increase Arterial P-contractility and VR increase before TPR decrease
Term
phase of ex adjustment
Definition
based on circulations ability to meet metabolic demands
Term
coronary artery disease
Definition
CAD
obstruction w/o damage to heart tissue
Term
coronary heart disease
Definition
CHD
obstruction w damage to the heart
Term
prinzmetal/varient angina
Definition
ST elevation
occurs at rest often in AM
releived with activity due to vasodialtions
caused by spasm
releived with nitro
Term
chronic/stable angina
Definition
predictable
onset with exertion
often occurs at certain HR
Term
unstable angine
Definition
symptoms in the absence of demands
higher mortality morbidity
a deterioration of stable angina
at rest abnormal response to activity
Term
cardiac muscle disfunction
Definition
most common cause of CHF
inability to pump
left vent cant accept blood
supplemental O2 alter body position
Term
Decompensated CHF
Definition
not being treated with meds
dont passivly increase VR
Term
compensated CHF
Definition
treated with meds
passivley increaseing VR can reduce symptoms
Term
Right CHF
Definition
congestion to lungs
presents with systemic edema
Term
Left CHF
Definition
Congestion in systemic circulation
dyspnea cough
Term
cheyne stokes respiration
Definition
decompensation of normal breatrhing patterns
Term
hypertension
Definition
>120/80
HTN
Left vent hypertrophy
left vent less compliant
increase LVEDP load L atria
Term
dialted cardiomyopathies
Definition
vent dialtion
no hypertrophy or vent wall thickning
increased LVEDV and LVEDP
decreases SV increases HR to compensate
s3-s4 gallop, cardiomegaly, murmur due to valve regurgitation
Term
hypertrophic cardiomyopathy
Definition
increased mass without dialtaion
impairs vent filling
increase LVEDP
Term
restrictive cardiomyopathy
Definition
decreased filling due to rigid tissue decreased compliance
