Chapter 4 general study Flashcards
Ventricular Septal Defect
is an abnormal opening in the septum dividing the left and right ventricles
Coronary Occlusion
refers to a complete blockage of a coronary artery
Endocardium
is the membrane on the inside surface of the heart
Tricuspid Valve
has three flaps of tissue to prevent backflow of blood.
Thrombophlebitis
refers to inflammation of a vein because of a blood clot
Defibrillator
is used to stop fibrillation of the heart
Myocardium
is the middle layer of the heart wall
Electrocardiograph
means a machine that records the electrical activity of the heart
Lymphedema
means swelling of the lymph nodes
Ischemia
refers to the restriction of blood to an area of the body because of constriction or obstruction of a blood vessel
Mediastinum
is an area in the middle of the chest that has the heart, its vessels, the esophagus, the trachea, and parts of the lymphatic system
Fibrillation
means a sudden and involuntary series of uncoordinated muscle contractions in the heart
Cardiomegaly
refers to enlargement of the heart
Valvular
means pertaining to a valve
Aortitis
means inflammation of the aorta
Blood Pressure
measures the pressure blood exerts on the arteries, veins, and chambers in the heart
Bradycardia
refers to slow heartbeat
Cardiopulmonary Resuscitation
reestablishes normal heart and lung action
Cardiac Catheterization
is a diagnostic procedure in which a catheter is inserted through a large vein and enters the heart
Lymph
is a fluid found in lymphatic vessels that contains lymphocytes
Holster monitor
portable electrocardiograph
telecardiography
a recording of a telecardiogram that travels long distances by impulses
cardiac computed tomography
produces cross sections of the heart.
cardiac MRI
magnetic resonance imaging of the heart
echocardiography
uses ultrasonic waves to monitor blood flow through the heart.
transesophageal echocardiogram
ultrasound test of the heart from inside the esophagus
thallium stress test
nuclear medicine procedure to measure cardiovascular function
arteriography
radiology of the arteries after injection of radiopaque material into the bloodstream.
aortography
radiology of the aorta after administration of a contrast medium.
coronary angiography/angiocardiography
radiology of the heart and its vessels by injection of contrast medium into coronary arteries.
digital subtraction angiography
computer enhanced images of blood vessels filled with contrast material
electrophysiology studies
uses electrode catheters inserted into the right side of the heart to identify disturbances in structures.
ventricular septal defect
abnormal opening in the septum dividing the right and left ventricles.
patent ductus arteriosus
an abnormal opening between the pulmonary artery and aorta.
coarctation of the aorta
narrowing of a part of the aorta
tetralogy of fallot
four congenital heart defects
cardiac arrest
aysytole (absence of pumping)
Heart block
impairment in conduction
paroxysmal atrial tachycardia
palpitations and fast heart beat that occur and stop suddenly
Congestive heart failure
insufficient oxygen to the heart that causes weakness, breathlessness, and edema
peripheral vascular disease
blockage or narrowing of arteries in lower extremities
cardioversion
uses electric shocks to restore the normal rhythm of the heart with direct-current shocks
bypass
A surgical procedure where a vessel is grafted to a blocked vessel so blood can flow normally
percutaneous coronary intervention
the management of coronary artery occlusions by catheter techniques
PTCA
A balloon expands the blood vessel
lymphogenous
producing lymph or produced by lymph
