25
Q

accelerated idioventricular rhythm

A

AV dissociation (consecutive VPCs) while HR under 160

26
Q

ventricular tachycardia

A

wide QRS with complete AV dissociation, HR more than 160, hemodynamically unstable! convert with lidocaine

27
Q

v fib

A

crazy rhythm, needs defibrillation

28
Q

abnormal VHS

A

dog 10.2
cat 7.8

29
Q

VLAS

A

more than 2.3 LAE and more than 3 needs vetmedin

30
Q

heart failure stages

A

A- predisposed
B1- murmur, only LV dilation OR LAE, slightly enlarged heart
B2- murmur, enlarged heart tx with pimobendan if murmur >3/6
C- congestive heart failure tx pimobendan, ACE-i and furosemide

31
Q

what can confound a BNP test

A

cleared through kidneys, CKD

32
Q

what drug is an inodilator

A

pimobendan (increases cAMP and intracellular calcium)

33
Q

which ACE inhibitor is almost all cleared through kidneys

A

enalapril

34
Q

restrictive cardiomyopathy in cats

A

atrial enlargement but normal ventricles

35
Q

ARVC in cats

A

RV and/or RA dilation due to fibrofatty replacement of myocardium, causes arrhythmias (tricuspid regurg common)

36
Q

secondary causes of LV hypertrophy in cats

A

systemic hypertension (CKD) and hyperthyroid

37
Q

tx for thromboembolism in cats

A

clopidogrel (LAE)

38
Q

reverse PDA

A

no murmur, differential cyanosis, high HCT, right sided CHF poor prognosis

39
Q

aberrant coronary

A

English bulldogs causes pulmonary stenosis

40

A

oncotic pressure

45
Q

examples of distributive shock (3)

A

sepsis, anaphylaxis, and excessive catecholamines

46
Q

examples of obstructive shock (4)

A

GDV, obstruction of vena cava, tension pneumo, and pericardial tamponade

47
Q

what percent of dehydration causes hemodynamic changes?

A

10-12%

48
Q

shock index

A

HR/SBP, should be less than 0.9

49
