cardiorespiratory system Flashcards
major symptoms of heart and lung dz
exercise intolerance, cough, dyspnea, weak, syncope, blue mm
symptoms of R and L sided HF
R sided- ascites, pitting edema, pleural effusion
L sided- cough, dyspnea, pulmonary edema
categories of murmur
I - IV ( I- quiet)
murmurs mostly systolic or diastolic
systolic
crackles indicate
fluid - edema or infection
wheezes indicate
infl, narrowing or airway
muffled lungs indicate
fluid or mass accumulation outside of lungs
causes of heart disease
blood clots, emboli, trauma, autoimmune, metabolic disease-hyperthyroidism/hypertension
this diet causes heart dz
taurine deficiency
high sodium
what causes mitral valve dz
genetic, wears with age, dental dz
symptoms of mitral valve dz
L apex murmur systolic. pulmonary edema
pulmonic stenosis refers to what side heart failure
right sided
aortic stenosis refers to
left sided HF
DCM
dilated cardiomyopathy
HCM
hypertrophic cardiomyopathy
commonly affected by DCM
dobermans and dogs
commonly affected by HCM
himalayan - maine coone
RCM
restricted cardiomyopathy
what occurs with RCM
pericardium constricts heart from pumping
“hardware disease”
RCM- cattle
thromboembolism occurs in cats with
HCM
heart malformation- left to right shunt, right sided failure- dogs
atrial septal defect ASD
heart malformation- right to left shunt, cats, horses
ventricular septal defect VSD
PRAA symptoms
persistant right aortic arch. GI signs, megaesophagus, regurgitate
PDA symptoms
patent ductus arteriosis. machinery type murmur, hyperperfusion of lungs and left sided volume overload
causes of arrhythmias
electrolyte imbalance. disruption of electrical system- ischema, cardiomyopathy. vagal tone, metabolic dz, drugs
Ascites indicates what sided HF, when there’s pressure where
Right. Vena cava
Pulmonary edema indicates what sided HF, when there’s pressure where
Left. Pulmonary vein
what drug is preferred for heart failure
pimobendin- inodilator
how many hw in dog/cat
dog- 250
cat- 3
best test for heartworm diagnosis
antigen test detects adult female worms
heartworm preferred concentration technique
modified knotts
immiticide drug name
melarsomine. 2-3 doses needed. adulticide
microfilaricide and larvacide
