Q

congestive heart failure

A

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

A

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

21
Q

dependent edema

A

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

22
Q

dilation

A

widening of tubular structure such as coronary artery

23
Q

dissecting aneurysm

A

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

24
Q

dysrhythmia

A

an irregular or abnormal heart rhythm

25
Q

hypertensive emergency

A

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

26
Q

infarction

A

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

27
Q

infarction

A

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

28
Q

inferior

A

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

29
Q

ischemia

A

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

30
Q

Lumen

A

the inside diameter of an artery or other Hollow structure

31
Q

myocardium

A

the heart muscle

32
Q

occlusion

A

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

33
Q

parasympathetic nervous system

A

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

34
Q

perfusion

A

the flow of blood through the body tissue and vessel

35
Q

posterior

A

the back surface of the body

36
Q

return of spontaneous circulation rosc

A

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

37
Q

stroke volume

A

the volume of blood ejected with each ventricular contraction

38
Q

Superior

A

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

39
Q

sympathetic nervous system

A

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

40
Q

syncope

A

a fainting spell or trenchant loss of consciousness

41
Q

tachycardia

A

a rapid heart rate, more than 100 beats per minute

42
Q

thromboembolism

A

a blood clot that has formed within a blood vessel and is floating within the bloodstream

43
Q

ventricle

A

one of two right and left lower chambers of the heart. The left ventricle receives blood from the left atrium upper chamber and delivers blood into the aorta. the right ventricle receives blood from the right atrium and pumps it into the pulmonary artery

44
Q

ventricular fibrillation

A

disorganized, and effective quivering of the ventricles, resulting in no blood flow and a state of cardiac arrest

45
Q

ventricular tachycardia

A

a rapid heart rhythm in which the electrical impulse begins in the ventricle instead of the atrium, which may result in inadequate blood flow and eventually deteriorate into cardiac arrest
