Flashcards in Chapter 5 Deck (55):
1

Anemia

A lower than normal number of erythrocytes in the blood

2

Aneurysm

A localized weak spot or balloon like enlargement of the wall of an artery

3

Angina

Condition of episodes of severe chest pain due to inadequate blood flow to the myocardium

4

Angioplasty

Procedure in which a small balloon is used to open a partially blocked coronary artery..."""

5

Anticoagulant

Slows coagulation and prevents new clots from forming

6

Aplastic anemia

Characterized by an absence of all formed blood elements caused by failure of blood cell production in the bone marrow

7

Arrhythmia

Describes the abnormality or the loss of the normal rhythm of the heart

8

Atherectomy

Surgical removal of plaque buildup from the interior of an artery

9

Atheroma

A deposit of plaque on or within the arterial wall

10

Atherosclerosis

Hardening and narrowing of the arteries caused by buildup of cholesterol plaque on interior walls of arteries

11

Atrial fibrillation

Normal rhythmic contractions of the atria replaced by rapid irregular twitching of muscular heart walls

12

Automated external defibrillator

For use by nonprofessionals in emergency situations when defibrillation is required

13

Beta-blocker

Reduces the workload of the heart by slowing the rate of the heartbeat

14

Blood dyscrasia

Any pathologic condition of the cellular elements of the blood

15

Bradycardia

Abnormally slow resting heart rate

16

Cardiac arrest

Event in which the heart abruptly stops or develops very abnormal arrhythmia that prevents it from pumping blood

17

Cardiac endarterectomy

Surgical removal of the lining of a portion of a clogged artery leading to the brain

18

Cardiomyopathy

All diseases of the heart muscle

19

Cholesterol

Fatty substance that travels through the blood and is found in all parts of the body

20

Chronic venous insufficiency

Venous circulation is inadequate due to partial vein blockage/leakage of venous valves

21

Coronary thrombosis

Damage to the muscle caused by a thrombus blocking a coronary artery

22

Defibrillation

The use of electrical shock to restore the hearts normal rhythm

23

Diuretic

Administered to stimulate the kidneys to increase the secretion of urine to rid the body of excess sodium and water

24

Electrocardiogram

A record of the electrical activity of the myocardium

25

Embolism

The sudden blockage of a blood vessel by an embolus

26

Embolus

A foreign object, such as a blood clot, quantity of air or gas, or a bit of tissue/tumor that is circulating though the blood

27

Endocarditis

Inflammation of the inner lining of the heart

28

Erythrocytes

Mature red blood cells produced by the red bone marrow (red blood cells-RBC)

29

ACE inhibitor

Blocks the action of the enzyme that caused the blood vessels to contract resulting in hypertension

30

Hemoglobin

The iron-containing pigment of the erythrocytes

31

Hemolytic anemia

A condition of an inadequate number of circulating red blood cells due to premature destruction of red blood cells by the spleen

32

Hemostasis

To stop or control bleeding

33

Ischemic heart disease

Group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart

34

Hemostasis

To stop or control bleeding

35

Ischemic heart disease

Group of cardiac disabilities resulting from an insufficient supply of oxygenated blood to the heart

36

Leukemia

Cancer characterized by progressive increase in # of abnormal WBC found in blood-forming tissues and in blood

37

Megaloblastic anemia

Blood disorder characterized by anemia in which RBC are larger than normal

38

Myelosplastic syndrome

Group of bone marrow disorders that are characterized by insufficient production of one or more types of blood cells

39

Myocardial infarction

Occlusion of one or more coronary arteries caused by plaque build up

40

Orthostatic hypotension

Low BP that occurs when standing up

41

Paroxymal atrial tachycardia

Episode that begins and ends abruptly where there are rapid and regular heartbeats originating in atrium

42

Pericardium

Surrounds and encloses the heart

43

Pernicious anemia

Anemia caused by lack of protein that helps the body absorb B12 from G.I. tract

44

Phlebitis

Inflammation of vein

45

Raynaud's phenomenon

Peripheral arterial occlusive disease in which intermittent attacks are triggered by cold or stress

46

Septicemia

Caused by the presence of bacteria in blood

47

Tachycardia

Abnormally rapid resting heartbeat usually more than 100 BPM

Thallium stress test

Performed to evaluate blood flow to heart during exercise by injecting small amount of thallium into blood

Abnormally small number of platelets circulating in blood

51

Thrombosis

Abnormal condition of having a thrombus
