Cardiology and Lymphatics Flashcards
ablation
therapeutic destruction of a body part, pathway, or function using surgery, chemicals, electrocautery, or radio frequency
angioplasty
endo-vascular procedure that reopens narrowed blood vessels
apical pulse
pulse felt or heard over the apex of the heart
artifact
signal interference on an ECG caused by patient movement, faulty equipment, or other factors
blood pressure
tension exerted by blood against the arterial walls during ventricular contraction and relaxation
cardiac cycle
one complete contraction and relaxation cycle of the heart
cardioversion
restoration of normal sinus rhythm by chemical or electrical means
depolarization
electrical change in cells in which the inside becomes positive in relation to the outside
diastole
pariod of cardiac muscle relaxation when blood is filling the chambers of the heart and blood pressure is lowest
electrocardiogram
record or tracing of electrical activity of the heart
electrocardiograph
instrument used to record an electrocardiogram
electrocardiography
process of recording the electrical activity of the heart
ligation
application of a band, thread, or wire to tie a blood vessel or other structure in order to constrict or fasten it
lumen
space within a vessel or other tubelike structure
lymph
clear, colorless, alkaline fluid found within lymph vessels made up of water, protein, salts, urea, fats, and white blood cells
palpitation
sensation of rapid or irregular beating of the heart sometimes described as a thudding or fluttering sensation
perfusion
circulation of blood, nutrients, and oxygen through tissues and organs
phagocytosis
process in which specialized white blood cells engulf and destroy microorganisms, foreign antigens, and cellular debris
pressure point
point at which an artery may be compressed to decrease blood flow in the event of hemorrhage
systemic circulation
circulation throughout the entire body
systole
period during contraction of chambers of the heart when blood pressure is the highest
systolic pressure
tension exerted against arterial walls during ventricular contraction and represented by the top number in a blood pressure reading
troponin
protein that is released into the blood by damaged heart muscle and, therefore, a highly sensitive and specific indicator of recent myocardial infarction
aden/o
gland
