20 Cards in this Set

  • Front
  • Back
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
