Question 6

aortic aneurysm

Answer 6

a weakness in the wall of the aorta and that makes it so susceptible to rupture

Question 7

aortic valve

Answer 7

the the the one-way valve that lies between the left ventricle and the aorta and keeps blood from flowing back into the left ventricle after the left ventricle ejects blood into the aorta. one of the four heart valves

Question 8

artifact

Answer 8

a tracing on ECG that is the result of the interference, such as patient movement, rather than the heart electrical activity

Question 9

asystole

Answer 9

the complete absence of all electrical activity

Question 10

atherosclerosis

Answer 10

a disorder in which cholesterol and calcium buildup inside the wall of blood vessels eventually leading to partial or complete blockage of blood flow

Question 11

atrium

Answer 11

one of two right and left upper chambers of the heart. the right atrium receives blood from the vena cava and delivers it to the right ventricle. The left atrium receives blood from the pulmonary veins and delivers it to the left ventricle.

Question 12

automaticity

Answer 12

the ability of cardiac muscle cells to contract without stimulation from the nervous system

Question 13

autonomic nervous system

Answer 13

the part of the nervous system that controls involuntary activities of the blood such as a heart rate, blood pressure, and digestion of food

Question 14

bradycardia

Answer 14

they still heart rate less than 60 beats per minute

Question 15

cardiac arrest

Answer 15

when the heart fails to generate effective and detectable blood flow. Pulses are not palpable in Cardiac Arrest, even if muscular and electrical activities continues in the heart

Question 16

cardiac output

Answer 16

a measure of the volume of blood circulated bye the heart in one minute, calculated by multiplying the stroke volume by the heart rate

Question 17

cardiogenic shock

Answer 17

a state in which not enough oxygen is delivered to the tissue of the body, caused by lower output of blood from the heart. It can be severe complication of a large acute myocardial infarction, as well as other conditions

Question 18

congestive heart failure

Answer 18

a disorder in which the heart loses part of its ability to effectively pump blood, usually as a result of damage to the heart muscle and usually resulting and a backup of fluid into the lungs

Question 19

coronary arteries

Answer 19

the blood vessels that carry blood and nutrients to the heart muscle

Question 20

defibrillate

Answer 20

to shock a defibrillating chaotically Beating Heart with specialized electrical current in an attempt to restore a normal rhythmic beat

Question 21

dependent edema

Answer 21

swelling in the part of the body closest to the ground, caused by collection of fluid in the tissue. a possible sign of congestive heart failure

Question 22

dilation

Answer 22

widening of tubular structure such as coronary artery

Question 23

dissecting aneurysm

Answer 23

a condition in which the inner layer of the artery such as the aorta become separated allowing blood at high pressure to flow between the layers

Question 24

dysrhythmia

Answer 24

an irregular or abnormal heart rhythm

Question 25

hypertensive emergency

Answer 25

an emergency situation created by excessive high blood pressure, which can lead to serious complications such as stroke or aneurysm

Question 26

infarction

Answer 26

death of a body tissue, usually caused by Interruption of its blood supply

Question 27

infarction

Answer 27

death of a body tissue, usually caused by Interruption of its blood supply

Question 28

inferior

Answer 28

the part of the body or any body nearer to the feet

Question 29

ischemia

Answer 29

a lack of oxygen that deprives tissue of necessary nutrients, resulting from partial or complete blockage of blood flow. Potentially reversible because permanent injuries has not yet occurred

Question 30

Lumen

Answer 30

the inside diameter of an artery or other Hollow structure

Question 31

myocardium

Answer 31

the heart muscle

Question 32

occlusion

Answer 32

a blockage, usually of a tubular structure such as a blood vessel

Question 33

parasympathetic nervous system

Answer 33

the part of the autonomic nervous system that controls vegetative functions such as digestion of food and relaxation

Question 34

perfusion

Answer 34

the flow of blood through the body tissue and vessel

Question 35

posterior

Answer 35

the back surface of the body

Question 36

return of spontaneous circulation rosc

Answer 36

the return of a pulse and effective the return of a pulse and effective ball at blood flow to the body in a patient who previously was in cardiac arrest

Question 37

stroke volume

Answer 37

the volume of blood ejected with each ventricular contraction

Question 38

Superior

Answer 38

the part of the body or any body part near to the Head

Question 39

sympathetic nervous system

Answer 39

the part of the autonomic nervous system that controls active function such as responding to fear also known as fight or flight

Question 40

Answer 40

a fainting spell or trenchant loss of consciousness
