Cardiovascular Pharmacology: Vet Tech

Front 1

diastole

Back 1

dilatation of the ventricles

Front 2

systole

Back 2

contraction of the ventricles

Front 3

ectopic

Back 3

arising from an abnormal site

Front 4

arrhythmia

Back 4

irregularity of the normal heart rhythm

Front 5

tachycardia

Back 5

increased heart rate

Front 6

bradycardia

Back 6

decreased heart rate

Front 7

flutter and fibrillation

Back 7

rapid series of irregular contractions due to a disorganization of electrical activity and probably relating to an ectopic pregnancy

Front 8

inotropic

Back 8

affecting the force (strength) of heart contraction

Front 9

chronotropic

Back 9

affecting the rate of heart rhythm

Front 10

cardiac

Back 10

pertaining to the heart

Front 11

afterload

Back 11

resistance in arteries that must be overcome to empty the ventricles

Front 12

preload

Back 12

the volume of blood that fills the ventricles during diastole

Front 13

dilatation

Back 13

the myocardium becomes thin and ineffective in its pumping action

Front 14

hypertrophy

Back 14

the myocardium become thickened and restricts ventricular filling

Front 15

output

Back 15

the volume of blood pumped per minute of time; cardiac output can be estimated clinically by measuring heart rate, pulse quality, and capillary refill time (perfusion)

Front 16

furosemide

Back 16

Lasix®

Front 17

digoxin

Back 17

Lanoxin®
Cardoxin®

Front 18

positive inotropes

Back 18

increase the force or strength of heart contraction

Front 19

negative inotropes

Back 19

decrease the force of strength of heart contractions

Front 20

positive chronotropes

Back 20

increase the heart rate

Front 21

negative chronotropes

Back 21

decrease the heart rate

Front 22

early signs of digoxin toxicity

Back 22

anorexia, vomiting, diarrhea

Front 23

group of drugs derived from the purple foxglove plant

Back 23

digitalis glycoside or cardiac glycoside

Front 24

Animals that digoxin toxicity is especially dangerous to

Back 24

hypokalemic (low blood potassium due to diuretics used in cardiac therapy)

Front 25

isoxsuprine

Back 25

Vasodilan®

Front 26

dobutamine

Back 26

Dobutrex®

Front 27

positive inotropes used to treat heart failure

Back 27

dobutamine, glucagon, calcium

Front 28

Cardiomyopathy

Back 28

disease of heart muscle progressing to congestive heart failure that primarily affects dogs and cats

Front 29

hypertrophic cardiomyopathy

Back 29

results when muscle wall of the heart thickens and reduces the size of the heart chamber until the ventricles cannot fill adequately with blood
(diastolic problem)

Front 30

dilated cardiomyopathy

Back 30

occurs when the muscle wall of the heart becomes thin and the heart loses its pumping action (systolic problem)

Front 31

dilated cardiomyopathy is more common in these dog breeds

Back 31

Doberman Pinscher, Great Dane, Irish Wolf Hound, St. Bernard, Bull Mastiff, Newfoundland, Golden Retriver, Irish Setter, Labrador Retriever

Front 32

Name a complication of cardiomyopathy in cats

Back 32

thromboembolism

Front 33

Breeds of cats most prone to hypertrophic cardiomyopathy

Back 33

Persian, Maine Coon

Front 34

Breeds of cats more prone to dilated cardiomyopathy

Back 34

Siamese, Burmese

Front 35

Dietary cause for dilated cardiomyopathy in cats

Back 35

taurine deficiency

Front 36

premature ventricular contraction (PVC)

Back 36

occurs when an ectopic focus is the ventricles causes the ventricles to contract too quickly (prematurely)

Front 37

propranolol

Back 37

Inderal®

Front 38

atenolol

Back 38

Tenormin®
