Q

What drug class is digoxin?

Study These Flashcards
A

Cardiac glycoside

22
Q

What is a cardiac glycoside?

Study These Flashcards
A

Inhibits the activity of ATpase that controls the movement of Ca, K+, Na in the heart muscle.
Holds Ca in the heart muscle to increase strength of contractions.

23
Q

What does giving digoxin do ?

Study These Flashcards
A

Holds Ca in the heart muscle for stronger contractions
Chronotropic
Positive inotrope
Slows electrical
Activity between the atria and the ventricule

24
Q

When do they use digoxin?

25
What is the concern about potassium levels while taking digoxin?
Low potassium in the body can give you digitalis toxicity
26
What is the normal range for dog levels?
0.5-2.0 For arrhythmia 0.5-0.9 for heart failure
27
Where is the blockage if you have elevations in leads II, III, AVF? What vessel?
Inferior, RCA
28
Where is the infarct for EKG changes in v1-v6? Vessels?
Anterior septal | LAD or LCerc
29
Changes in lead 1, AVL, V5 V6? | Vessels?
Lateral wall | LAD or circ
30
What are the signs and symptoms of pulmonary valve stenosis?
Right heart failure | Peripheral edema, JDV, dyspnea on exertion light headedness
31
How does dobutamine work?
Increases contractility but causes vasodilation to decrease systemic vascular resistance.
32
What does dopamine do?
Increases contractility and increases SVR
33
What is the cause of restricted cardiomyopathy?
S-scar tissue build up C-Chemotheropthy A-amyloidosis R-Radiation exposure of the chest Idiopathic
34
Signs and symptoms of restricted cardiomyopathy
Shortness of breath (at first with exercise; but over time it occurs at rest) Fatigue (feeling overly tired) Inability to exercise Swelling of the legs and feet Weight gain Nausea, bloating, and poor appetite (related to fluid retention) Palpitations (fluttering in the chest due to abnormal heart rhythms)
35
What are hallmark values in restricted cardiomyopathy?
Elevated right atrial pressure Left ventricular diastolic disfunction occurs.... which is associated with very high end diastolic pressures and moderate to marked atrial enlargement Normal systolic function
36
What patients are at risk for developing contrast-induced nephropathy when admitted for a carotid arteriogram?
Hypovolemic Anemic Take metformin Anti rejection meds (cyclosporine)
37
What sound do you hear with a VSD?
Pansystolic mid-high pitch at the left sternal boarder
38
What does Holotsystolic murmur mean?
A holosystolic murmur begins at the first heart sound (S1) and continue to the second heart sound (S2), as illustrated in the phonocardiogram. Typically high-pitched, these murmurs are usually caused by ventricular septal defect, mitral regurgitation or tricuspid regurgitation, as discussed below.
39
Where can you hear Holotsystolic murmurs?
Holosystolic murmurs can be auscultated over the left 3rd and 4th intercostal spaces and along the sternal border.
40
What heart soundnis made with a tricuspid regurg?
There is a loud, , pansystolic (holosystolic) murmur. , rumbling, diamond-shaped diastolic murmur.
41
Where can you hear a Tricuspid regurg?
Harsh systolic murmur, the maximum intensity is heard at the left lower sternal border. In addition, the murmur intensity increases with inspiration.
42
What does PAOP measure?
Pulmonary capillary wedge pressure (PCWP) provides an indirect estimate of left atrial pressure (LAP).
43
Why measure PAOP?
severity of left ventricular failure and to quantify the degree of mitral valve stenosis.
44
What elevates left atrial pressure therefore elevating PAOP?
Left ventricular failure Mitral stenosis Mitral regurg Aortic stenosis aortic regurg
45
How high does left atrial | Pressure have to be to start pulmonary edema?
above 20 mmHg,
46
What is Milrinone?
Inotrope and vasodilator
47
When do you use milrinone?
heart failure. stroke volume and cardiac output are increased a slight fall in mean systemic arterial pressure. Decr. SVR coronary vasodilator
48
What murmur is heard with mitral valve stenosis?
Rumbling diastolic murmur loaders at the apex
49
What is heard with an aortic stenosis?
Musical systolic murmur loudest right sternal boarder
50
What is Wolff-Parkinson’s-white syndrome?
An extra electrical pathway between the atria and the ventricle
51
Signs and symptoms of pericarditis?
Sharp chest pain can radiate to left shoulder or neck | Feels better when lean forward.
52
What ekg changes do you see with pericarditis?
Diffuse ST elevation With an upward concavity
