P wave
26
Precedes ventricular systole
QRS complex
27
Precedes ventricular diastole
T wave
28
Coronary artery supplies
Myocardium
29
During ventricular systole
Blood is under great pressure, top number of blood reading
30
During ventricular diastole
Blood isn't being pushed from heart at all, blood pressure drops to lowest point
31
Record of a vessel
Angiogram
32
Inflammation of a vessel
Angiitis
33
Surgical repair of vessel
Angioplasty
34
Ruptured artery
Arteriorrhexis
35
Surgical removal of fatty substance
Atherectomy
36

42
Listening to sounds within body using a stethoscope
Auscultation
43
Area of necrotic tissue due to loss of blood supply
Infarct
44
Local and temporary deficiency of blood supply due to a circulatory obstruction
Ischemia
45
Abnormal heart sound such as soft blowing sound or a harsh click
Murmur
46
To flow backwards
Regurgitation
47
Electrical impulse is blocked from traveling down bundle branches; results in ventricles beating at different rate than atria
Bundle branch block (BBB)
48
Myocardial disease, may be caused by viral infection, congestive heart failure, or alcoholism
Cardiomyopathy
49
Left ventricle muscle is too weak to efficiently pump blood, results in weakness, breathlessness, and edema
Congestive heart failure (CHF)
50
Inflammation of lining membranes of heart; if cause is bacterial may have a bacterial colony form, called vegetation
Endocarditis
51
Extremely serious arrhythmia characterized by quivering of heart fibers, cardiac arrest and death can occur
Fibrillation
52
Arrhythmia in which atria beat to rapidly, but in a regular pattern
Flutter
53
Cusps are too loose and fail to shut tightly, allowing regurgitation
Heart valve prolapse
54
Cusps are too stiff, unable to shut tightly, allowing regurgitation
Heart valve stenosis
55
Occlusion of coronary artery; heart attack
Myocardial infarction (MI)
56
Weakness and ballooning of arterial wall; commonly seen in abdominal and cerebral arteries
Aneurysm
57
Hardening and loss of elasticity of arterial walls, often due to atherosclerosis
Arteriosclerosis
58
Liquid plaques form in arterial wall
Atherosclerosis
59
Obstruction of blood vessel by blood clot that has broken off from a thrombus in another site
Embolus
60
