25
Diabetes Mellitus
A disease in which the body does not control the amount of glucose (a type of sugar) in the blood and the kidneys make a large amount of urine. This disease occurs when the body does not make enough insulin or does not use it the way it should
26
Diaphoresis
Sweating
27
Diastole
Period of time when the heart muscle is relaxed and the chambers fill with bood
28
Ductus arteriosus
A temporary connection between pulmonary trunk and aorta in the fetal heart
29
Dyspnea
Difficulty breathing
30
Echocardiogram
A computer picture of the heart created by bouncing high-energy sound waves (ultrasound) off internal tissues or organs of the chest
31
Echocardiography
A procedure that uses high-energy sound waves (ultrasound) to look at tissues and organs inside the chest
32
Electrocardiogram (ECG/EKG)
The record of the heart's function produced by the electrocardiograph
33
Electrocardiograph
The instrument that generates an electrocardiogram (ECG); 10 electrodes are placed in standard locations on the patient's skin to record heart function
34
Electrocardiography
The science of recording the electrical activity of the heart
35
Endocarditis
A condition in which the tissues lining the inside of the heart and the heart valves become inflamed
36
Foramen Ovale
An opening between right and left atria, which is normal in the fetal heart
37
Great vessels
Include the superior vena cava, inferior vena cava, aorta and pulmonary trunk
38
Heart murmur
An abnormal heart sound
39
Heart rate
The number of times the heart beats within a certain time period, usually a minute
40
High-density lipoprotein (HDL)
Often referred to as "good" cholesterol
41
Hypercholestrolemia
Higher than normal levels of cholesterol in the blood
42
Hyperlipidemia
Excessive fat in the blood
43
Hypertension
Abnormally high blood pressure
44
Implantable cardioverter defibrillators (ICD)
A small device placed by surgery in the chest or abdomen that is used to correct a heartbeat that is abnormal. Wires are passed through a vein to connect the device to the heart. When it detects abnormal heartbeats, it sends an electrical shock to the heart to restore the heartbeat to normal.
45
Inferior vena cava
One of the two largest veins in the body. It carries oxygenated blood from the torso and legs back to the heart.
46
Interatrial septum
The wall separating the right and left atria
47
Interventricular septum
The wall of myocardium that separates the right and left ventricles
48
Ischemia
Lack of blood flow to body tissues
49
Low-density lipoprotein (LDL)
Often referred to as 'bad' cholesterol
50
Magnetic Resonance Imaging (MRI)
A procedure in which radio waves and powerful magnet linked to a computer are used to create detailed pictures of areas inside the body
51
Mitral valve
Located at the opening between the left atrium and left ventricle; also known as the bicuspid valve
52
Myocardial Infarction (MI)
A rare condition in which the heart muscle becomes thick and inflamed and may also become weak
53
Occlusion
a blockage
54
Pacemaker
An electronic device that is implanted in the body to monitor heart rate and rhythm. It gives the heart electrical stimulation when it does not beat normally
55
Palpitations
A rapid or irregular heartbeat that a person can feel
56
Pericardial fluid
Watery fluid produced in the serous and visceral pericardium surrounding the surface of the heart
57
Pericarditits
Inflammation of the (sac) surrounding the heart
58
Pericardiocentesis
Surgical puncture to aspirate fluid from the (sac) surrounding the heart
59
Plaque
A fatty material including cholesterol, connective tissue, white blood cells, and some smooth muscle cells
60
Polycythemia
A rare disorder in which the bone marrow produces and abnormally large amount of blood cells
61
Pulmonary trunk
The very large artery referred to as a trunk, a term indicating that the vessel gives rise to several smaller arteries
62
Roots of the great vessels
The part of each great vessel (aorta, pulmonary trunk, inferior vena cava, superior vena cava) that connects to the base of the heart.
63
Serous Membrane
One of the thin membranes that cover the walls and organs in the thoracic and abdominopelvic activities
64
Sinus rhythm
The normal electrical pattern followed by a contraction of the heart
65
Sphygmomanometer
A blood pressure cuff attached to a measuring device
66
Stethoscope
An instrument used to hear sounds produced by the heart, lungs, or other parts of the body
67
Superior vena cava
One of two large veins in the body, which carries deoxygenated blood from the heart and upper extremities back to the heart
68
Syncope
Fainting
69
Systole
Period of time when the heart is contracting
70
Tachycardia
A condition in which the resting rate is about 100bpm
71
Vavuloplasty
The widening of a stenosed heart valve using a balloon catheter
