25
atrial fibrillation is treated with _____ while ventricular fibrillation is treated with
drugs ; defibrillation to reset the heart
26
with right sided heart failure the blood is backing up into the ____, mainly in the ____. this backup can lead to fluid accumulation in the abdomen which is aka
body ; liver ; ascites
27
ARVC is commonly known as
boxer cardiomyopathy
28
patients with DCM may suddenly die, which is caused by ____ that occur with the disease process
atrial fibrillation
29
the foramen ovale should close within ___ hours of birth
24
30
ECGs are a common tool utilized in cardiology as they are relatively cheap and they measure the ___ of the heart
electrical activity
31
with left sided heart failure, blood is backing up into the ____, leading to fluid accumulation. we call this _____
lungs ; pulmonary edema
32
____ is the name for adult heartworms, while ___ is the name for immature HW
dirofilaria immitis ; microfilaria
33
the correct name for saddle thrombus is
thromboembolism
34
what is a bubble study and what is it used to diagnose
inject air bubbles into a vein to watch them flow into the heart, left or right shunts
35
what is the most common cause for atrial premature contractions
LA enlargement that is secondary to heart failure
36
which species are most affected by PDAs
dogs ; small breeds ; newfies ; collies ; labs
37
how do we treat polycythemia and why do we do this
therapeutic phlebotomy, blood becomes thicker and has trouble flowing normally
38
what would you find on a physical exam on a patient throwing VPCs
extra beat heard every so often with or without a pulse deficit
39
what is our goal in medically managing DCM in our patients
increasing CO2, decreased afterload, manage arrhythmias, treat / prevent edema accumulation
40
what are the 5 diagnostics that can be used to evaluate the CV system
auscultation, rads, ECHO, ECG, BW
41
what changes would we expect to see in regards to cardiac output in our pts with DCM
decreased CO, the heart is pumping less blood to the body than it should
42
whcih tachyarrhythmias would we expect to see in pts with DCM
a-fib or VPC
43
what is precordial thrill
able to feel the vibration from the murmur on the chest wall
44
what is caval syndrome
obstruction of blood flow into and through the heart, occurs in animals with a large worm burden
45
what can cause circulatory failure in patient
hypovolemia, anemia, valvular dysfunction, congenital shunts
46
what are the clinical signs associated with PRAA
regurg of solid food, aspiration pneumonia, fever, dyspnea, cough, wt loss
47
what are the three things that can cause myocardial dysfunction
cardiomyopathy, myocarditis, taurine deficiency in cats
48
clinical signs of R CHF
ascites, hepatomegaly, wt loss, abdominal distension
49
define asystole
lack of ventricular activity
50
saddle thrombi generally occur in which major blood vessel
aorta
51
what is the intermediate host for heartworms
female mosquito
52
how is hw treated
immiticide, melarsamine, ivermectin, sx to remove
53
what are the most common stenotic valves seen in vet med
pulmonic, aortic, subaortic
54
why is v-fib such a concern
ventricles are moving chaotically, treated as cardiac arrest, essentially no CO
55
which type of arrhythmia sounds like shoes in the dryer
atrial fibrillation
56
what can septal defects lead to in our pts
shunts, CHF by 8 weeks of age
57
what is polycythemia, what hormone stimulates this to occur
increased number of RBC, erythropoietin
58
what is a heart murmur and how can it be described
abnormal heart sound, backflow of blood through the valves of the heart
59
how do cats with a saddle thrombus typically present
vocalizing, cyanosis of hindlimb, cold hindlimbs, paaralysis of one or both hindlimbs
60
how are septal defects typically treated in our pts
managing the CHF and pt comfort with medication
61
two heartworm testing method other than antigen testing
modified knotts, PCV
62
when are most cases of congenital heart dz found on our pts
first vet visit
63
3 blood test that can be done to measure cardiac enzymes
BNP ANP, tropinin-1
64
what is reperfusion injury and why is it a problem
restricted blood flow, build of of toxins, necrotic, CV collapse
65
what is PRAA and what is happening with this dz
persistent right aortic arch, persistence of the right 4th aortic arch that wraps around the esophagus and causes and obstruction
66
what dog breed is/are susceptible to ivermectin toxicities
collies
67
what is going on with tetralogy of fallot
pulmonic stenosis, R ventricular hypertrophy, subaortic ventricular septal defect, overriding aorta
68
clinical signs associated with L CHF
coughing, pulmonary edema, syncope
69
where do young adult hws mature into adults, where do they end up w a heavy worm burden
pulmonary artery, end up in right atrium
70
arrhythmias are usually the result of
cardiomyopathy, hypocalcemia, hyperkalemia, hypercalcemia, ischemia
71
what is PDA and what happens when it fails to close
patent ductus arteriosus, when it fails to close, blood shunts from the aorta to the pulmonary artery
72
why do we no longer see DCM diagnosed with our feline pts
taurine in the diets
73
define arrhythmia
any deviation from normal heart rhythm
74
what is MMVD and who is at risk of this disease
myxomatous mitral valve disease ; mitral valve insufficiency ; dogs with severe periodontal disease
75
what is heart failure and how is it different than CHF
HF = heart looses ability to adequately pump blood CHF = heart failure and the accumulation of fluid build up
