Cardiovascular System 2 Flashcards
autonomic nervous system
Portion of the nervous system that regulates involuntary actions such as heart reate, digestion, and peristalsis
leaflet
Flat, leaf-shaped structure that comprises the valves of the heart and prevents back flow of blood
lumen
Tubular space or channel within an organ or structure of the body; space within an artery, vein, intestine or tube
regurgitation
Backflow or ejecting of contents through an opening
sphincter
Circular muscle found in tubular structure of hollow organ that constricts or dilates to regulate passage of substances through its opening
vasoconstriction
Narrowing of the lumen of a blood vessel that limits blood flow, usually as a result of diseases, medications, or physiological processes
vasodilation
Widening of the lumen of a blood vessel caused by the relaxing of the muscles of the vascular walls
viscosity
State of being sticky or gummy

angina
Mild to severe suffocating pain that typically occurs int he chest and is caused by an inadequate
arrhythmia
Irregularity in the rate or rhythm of the heart; dysrhythmia
bradycardia
Arrhythmia in which the heart beats abnormally slowly, usually fewer than beats per minutes in resting an adult
fibrillation
Arrhythmia in which there is an abnormally rapid, uncoordinated quivering of the myocardium that can affect the atria or the ventricles
heart block
Arrhythmia in which there is interference with the normal transmission of electric impulses from the SA node to the Purkinje fibers
tachycardia
Arrhythmia in which there is a fast but regular rhythm, with the heart possibly beating up to 200 bpm
arteriosclerosis
Hardening and narrowing of an artery along with the loss of its elasticity
carotid artery disease
Narrowing of the carotid arteries
bruit
Soft blowing sound heard on auscultation, associated valvular action or with the movement of blod as it passes an obstruction or both; murmur
cardiomyopathy
Disease or weakening of heart muscle that diminishes cardiac function
coarctation
Narrowing of a vessel, especially the aorta
embolism
Condition in which a mass become lodged in a blood vessel, obstructing blood flow
hyperlipidemia
Excessive amounts of lipids in the blood
hypertension (HTN)
Elevated blood pressure persistently higher than 140/90 mm Hg
hypotension
Low blood pressure persistently lower that 90/60 mm Hg
infarction
Localized tissue necrosis due to the cessation of blood supply
ischemia
Local, temporary deficiency of blood supply to an organ or tissue due to circulatory obstruction
mitral valve prolapse (MVP)
Structural defect in which the mitral valve leaflets prolapse into the left atrium during ventricular contraction resulting in incomplete closure and backflow of blood
palpitation
Sensation of an irregular heartbeat, commonly described as pounding, racing, skipping a beat or flutter
phlebitis
Inflammation of a deep or superficial vein of the arms or legs
syncope
Partial or complete loss of consciousness that is usually caused by a decreased supply of blood to the brain; fainting
thrombosis
Abnormal condition in which a blood clot develops in a vessel and obstructs it at the site of its formation
deep vein thrombosis (DVT)
Blood clot that forms in the deep veins of the body, especially thos in the legs or thighs
defibrillation
Electrical shock delivered randomly during the cariac cycle to treat emergency life threatening arrhythmias
cardioversion
defib using low energy techniques
sclerotherapy
Injection of a chemical irritant into a vein to produce inflammation and fibrosis that destroys the lumen of the vein
thrombolysis
Destruction of a blood clot using anticlotting agents called clot-busters such as tissue plasminogen activator
angioplasty
Any endovascular procedure that reopens narrowed blood vessels and restores foward blood flow
percutaneous transluminal coronary angioplasty (PTCA)
Angioplasty of the coronary arteries in which a balloon catheter is inserted through the skin into the right femoral artery and threaded to the site of the stenosis to enlarge the lumen of the artery and restore forward blood flow
biopsy
Removal of a small piece of tissue of diagnostic purposes
arterial
Remove of a segment of an arterial vessel wall to confirm inflammtion of the wall or arteritis
catheter ablation
Treatment for cardiac arrhythmias
commissurotomy
Surgical separation of the leaflets of the mitral valve
coronary artery bypass graft (CABG)
Placement of a vessel graft from another part of the body to bypass the blocked part of a coronary artery and restore blood supply to the heart muscle
embolectomy
Removal of embolus
endarterectomy
Removal of fatty plaque from the interior of an occluded vessel using a specially designed catheter fitted with a cutting or grinding device
automatic implantable cardioverter-defibrillator (AICD) insertion
Implantation of a battery-powered device that monitors and automatically corrects ventricular tachycardia or fibrillation by sending electrical impulses to the heart in patients who are at risk of sudden cardiac death
laser ablation
Procedure used to remove or treat varicose viens
open heart surgery
Surgical procedure performed on or within the exposed heart, usually with the assistance of a heart-lung machine
stent placement
Placement of a mesh tube inserted into a natural passage or conduit in the body to prevent or counteract a disease induced localized flow constriction
valvotomy
Incision of a valve to increase the size of the opening
cardiac catheterizaiton (CC)
Passage of a catheter into the heart through a vein or artery to provide a comprehensive evaluation of the heart

Procedure used to determine the cause of life-threatening cardiac arrhythias by mapping the heart’s conduction system in a patient with an arrhythmia
