Flashcards in Cardiovascular Deck (42):
1

The area oc the thorax that contains the heart and trachea.

Mediastinum

1

What is heart murmur often related to?


Periodontal disease

2


What seperates the left and right ventricles?


Interventricular septum

3

The impulse for the heart beat originates in the...?

SA Node

3

Which side of the heart moves blood to the body?

Left side

4

Vessel cranial to the heart

Axillary artery

5

What is the thickest layer of the heart?

Myocardium

6

What is happening to the heart muscle during the "P" phase of the PQRS complex?

The atria are contracting

6

What is asystole?

When the heart has completely stopped.

7

Condition in which the muscles of the heart have become thin and weak and now have a lower stroke volume than normal.


Dilated Cardiomyopathy

7

What are the most easily visible parts of the atria called?

Auricles

7

Which artery supplies blood to the tail?

Coccygeal

8

At the hind limbs, the trunk of the aorta divides into right and left______

Iliac arteries.

9

The 2 factors for cardiac output

Stroke volume and heart rate

11

What happens during diastole?

The heart relaxes and refills with blood

13

What happens during Systole?

Heart muscle contracts and blood leaves the atria to the ventricles or from the ventricles to the arteries.

14

what artery carries deoxygenated blood

pulmonary artery

15

what vein carries oxygenated blood

pulmonary vein

16

Where is the tricuspid valve located and what is another name for it?

Between the right atrium and right ventricle, right atrioventricular valve.

17

Between what two layers of the heart is there a fluid filled space and what is its purpose?

Visceral and parietal layers. The fluid acts as a lubricant to allow smooth expansion and contraction.

18

In what cardiac cycle does the heart relax and refill with blood to be ejected during the next systolic contraction?

Diastole

18

What is the difference between Sinus bradycardia and Sinus tachycardia?

Sinus bradycardia Abnormally slow heart rate Normal conductivity Sinus tachycardia Abnormally fast heart rate Normal conductivity

19

In what cardiac cycle does the heart muscle contract, eject blood from the atria to the ventricles, and then from the ventricles to the arteries?

Systole

21

 What keeps the valve between the atrium and the ventricle from bending back into the atrium

Chordae tendineae

22

oval opening that alows blood to by pass the fetus's lungs

Foramen ovale

23

What is the caudal bend of the heart

The Apex

24

Instrument that is used to measure electrical activity of the heart

Electrocardiogram

25

Normal feline Heart Rate

150-210bpm

27

Normal Canine Heart Rate

70-160 bpm

28

Where is the mitral valve located and what is another name for it?

Between the left atrium and left ventricle, left atrioventricular valve.

29


Pulse Deficit

When the heart rate and pluse rate are not the same

30


Normal Feline Heart Rate

150-210 bpm

32

The vein most commonly used for venipuncture is the____vein?

Jugular

33

What 2 factors control cardiac output?

Stroke Volume and Heart Rate

35

what are the 3 things we can change to manage heart disease?

Pump - strength of the beat, Pipes - constrictict or dilate vessels, Fluid - viscosity

36

What is the electrical anatomy of the heart?

SA Node, AV Node, Bundle of His, Purkinje Fibers

37

What does the T wave represent?

relaxing of the ventricle and recharging of the node

38

What is the outer layer of the heart called? 

Pericardium

39

What is the order of blood flow?

Vena cava

Right Atrium

Tricuspid valve

Right ventricle

Pulmonary valve

Pulmonary artery

Lungs

Pulmonary vein

Left atrium

Mitral valve

left ventricle

aortic valve

aorta

Systemic circulation

40

The chordae tendineae connect to the _______ muscles

Papillary

41

What does SA node stand for?

Sinoatrial node

42


the mitral valve separates what 2 chambers of the heart

left atrium and the left ventricle
