Chapter 11: Need to Know Terms Flashcards
aorta
largest artery in the body
arteriole
small artery
artery
largest type of blood vessel; carries blood away from the heart to all parts of the body
coronary arteries
blood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle
deoxygenated blood
blood that is oxygen-poor
diastole
relaxation phase of the heartbeat (Greek diastole, dilation)
electrocardiogram
record of the electricity flowing through the heart. electricity is represented by waves or deflections called P, QRS, or T
endocardium
inner lining of the heart
endothelium
innermost lining of blood vessels
mitral valve
value between the left atrium and the left ventricle; bicuspid valve
murmur
abnormal swishing sound caused by improper closure of the heart valves
myocardium
muscular, middle layer of the heart
septum
septa
four chambers of the heart separated by partitions
sphygmomanometer
instrument to measure blood pressure
systole
contraction phase of the heartbeat. (Greek systole, contraction)
tricuspid valve
located between the right atrium and the right ventricle; it has three leaflets, or cusps
valve
structure in veins or in the heart that temporarily closes an opening so that blood flows in only one direction
vein
thin-walled vessel that carries blood from body tissues and lungs back to the heart. veins contain valves to prevent backflow of blood
ventricle
one of two lower chambers of the heart
venule
small vein
auscultation
listening to the internal sounds of the body
arrhythmias
abnormal heart rhythms
flutter
rapid but regular contractions, usually of the atria
fibrillation
very rapid, random, inefficient and irregular contractions of the heart (350 or more beats per minute)
atrial fibrillation (AF)
most common type of cardiac arrhythmia
palpitations
uncomfortable sensations in the chest from missed heartbeats
ventricular fibrillation (VF)
electrical impulses move randomly throughout the ventricles
implantable cardioverter-defibrillator (ICD)
small electrical device that is implanted inside the chest to sense arrhythmias and terminate them with an electric shock
congestive heart failure (CHF)
heart is unable to pump its required amount of blood
congenital heart disease
abnormalities in the heart at birth
CABG
coronary artery bypass grafting
PCI
percutaneous coronary intervention
endocarditis
inflammation of the inner lining of the heart
MVP
mitral valve prolapse
bruit
abnormal blowing or swishing sound heard during auscultation of an artery or organ
thrill
vibration felt over an area of turmoil in blood flow
aneurysm
local widening (dilation) of an arterial wall
AAA
abdominal aortic aneurysm
DVT
deep vein thrombosis
PAD
peripheral arterial disease
angina
chest pain resulting from myocardial ischemia
cardiac arrest
sudden, unexpected stoppage of heart action, often leading to sudden cardiac death
embolus
emboli
clot or other substance that travels to a distant location and suddenly blocks a blood vessel
infarction
area of dead tissue
occlusion
closure of a blood vessel due to blockage
pericardial friction rub
scraping or grating noise heard on auscultation of the heart
vegetations
clumps of platelets, clotting proteins, microorganisms, and red blood cells on diseased heart valves
BNP Test
measurement of BNP ( brain natriuretic peptide) in blood
lipid tests (lipid profile)
measurement of cholesterol and triglycerides (fats) in a blood sample
lioprotein electrophoresis
lipoproteins (combinations of fat and protein) are physically separated and measured in a blood sample
angiography
x-ray imaging of blood vessels after injection of contrast material
cardiac catheterization
thin, flexible tube is guided into the heart via a vein or an artery
electrocardiography (ECG)
recording of electricity flowing though the heart
(ECG)
electrocardiography
Holter monitering
an ECG device is worn during a 24-hour period to detect cardiac arrhythmias
endarterectomy
surgical removal of plaque from the inner layer of an artery
PCI
percutaneous coronary intervention
AF, a-fib
atrial fibrillation
BP
blood pressure
CABG
coronary artery bypass grafting
CAD
coronary artery disease
CCU
coronary care unit
CHF
congestive heart failure
CPR
cardiopulmonary resuscitation
DVT
deep vein thrombosis
ECG or EKG
electrocardiography
ECHO
echocardiography
ETT
exercise tolerance test
MI
myocardial infarction
MVP
mitral valve prolapse
SOB
shortness of breath
SVT
supraventricular tachycardia; rapid heartbeats arising from the atria and causing palpitations, SOB, and dizziness
