Cardiac pt 3 Flashcards
describe the alteration of chamber compliance for all 3 cardiomyopathies
dilated - inc
hyper - dec (LV mainly)dec
restric - dec (LV mainly)
myocarditis
inflammation of the heart muscle
pericarditis
inflammation of the pericardium
describe ASD
opening between the atria allowing blood to flow from LA to RA
what is coarctation of the aorta
narrowing of the aorta
what are some commonly used criteria to diagnose HF
dyspnea
crackles
pulm edema
S3 sound
tachycardia
cardiomegaly
what are the 4 parts of tetralogy of fallot
large VSD
pul stenosis
overriding aorta
RV hypertrophy
what is the end stage result of cardiomyopathies
low ejection fraction
is stenosis quick or does it take time to develop
develops slowly over years
what is the most common cause of sudden cardiac death in young athletes
hypertrophic cardiomyopathy
Valve Insufficiency
inability of a valve to close completely
what are some clinical manifestations of cardiomyopathies
dyspnea
orthopnea
low exercise tolerance
fatique
weakness
arrhytmia
what is the ejection fraction
the percentage of blood ejected vs what was in the LV
s2 sounds
closure of semilunar valves at end of systole
describe VSD
opening between the ventricles allowing blood to flow from LV to RV
what experiences hypertrophy with mitral stenosis
LA
diasoltic HF has what effect on EF
equal or above 50%
what side HF leads to RV hypertrophy
left side
Heart sound: closure of semilunar valves at end of systole
S2 sound
higher ventricular wall tension leads to what with HF
myocyte growth
hypertrophy
what happens to the LA pressure with aortic regurgitation
it increases
what are the 4 acyanotic defects
ASD
VSD
Coarctation of the aorta
PDA
describe LV contractility with aortic stenosis
it goes down
describe trucus arteriosus
aorta and PA are one vesel that recives blood from both sides of the heart
increases LA pressure with mitral stenosis has what affect on the LA
dilation leading to fibrilation and palpations
what is a normal EF
60-80%
what does the baroreceptor response do for HF
inc HR
inc contractility
what HF leads to pulmonary congestion
Left side
what are the cyanotic defects
tetralogy of fallot
transpotion of the great arteries
truncus arteriosus
