|
coronary arteries
|
the blood vessels that supply blood to the heart. (they start at the first part of the aorta)
|
|
|
ischemia
|
chest pain or discomfort that is related to the heart, or insufficient oxygen
|
|
|
acute myocardial infarction (AMI)
|
heart attack; death of heart muscle following obstruction of blood flow to it. (acute = new, happening right now. 40% of AMI PT's do not survive the ride to the hospital)
|
|
|
angina pectoris
|
transient (short-lived) chest discomfort caused by partial or temporary blockage of blood flow to the heart.
(30 minutes after blood flow is cut off, some heart muscles begin to die) |
|
|
arrhythmia
|
an irregular or abnormal heart rhythm
|
|
|
asystole
|
complete absence of heart electrical activity (flat line)
|
|
|
cardiac arrest
|
a complete cessation of cardiac activity. a state in which the heart fails to generate an effective and detectable blood flow; pulses are not palpable in cardiac arrest
|
|
|
Nodes of the Heart
|
SA then AV then purkinje fibers
|
|
|
Cardiogenic Shock
|
a state in which not enough oxygen is delivered to the tissues of the body, caused by low output of blood from the heart.
- onset is immediate and can be unapparent for 24 hrs - heart lacks power to force blood |
|
|
angioplasty
|
an operation to repair a damaged blood vessel or unblock a coronary artery
|
|
|
Coronary Artery Bypass Graft (CABG)
|
a vein taken from the entire length of the leg is used to replace or fix an artery in the heart
|
|
|
Congestive Heart Failure (CHF)
|
a disorder in which the heart loses part of its ability to effectively pump blood, usuall as a result of damage to the heart muscles and usually resulting in a backup of fluid into the lungs.
|
|
|
dependent edema
|
swelling in the part of the body closest to the ground, caused by collection of fluid in the tissues; a possible sign of CHF
|
|
|
dilation
|
widening of a tubular structure such as a coronary artery
|
|
|
infarction
|
death of a body tissue, usually caused by interruption of its blood supply
|
|
|
lumen
|
the inside diameter of an artery or other hollow structure
|
|
|
occlusion
|
blockage, usually of a tubular structure such as a blood vessel
|
|
|
syncope
|
fainting spell or transient loss of consciousness
|
|
|
ventricular fibrillation
|
disorganized, ineffective twitching of the ventricles, resulting in no blood flow and a state of cardiac arrest
|
|
|
ventricular tachycardia
|
rapid heart rhythm in which the electrical impulse begins in the ventricle (instead of the atrium), which may result in inadequate blood flow and eventually deteriorate
|
