-
acute coronary syndrome (ACS)
a blanket term used to represent any symptoms related to lack of oxygen (ischemia) in the heart muscle. Also called cardiac compromise
-
acute myocardial infarction (AMI)
the condition in which a portion of the myocardium dies as a result of oxygen starvation; often called a heart attack by laypersons
-
agonal breathing
irregular, gasping breaths that precede apnea and death
-
aneurysm
the dilation, or ballooning, of a weakened section of the wall of an artery
-
-
pain in the chest, occurring when blood supply to the heart is reduced and a portion of the heart muscle is not receiving enough oxygen
-
-
asystole
a condition in which the heart has ceased generating electrical impulese
-
bradycardia
when the heart rate is slow, usually below 60 beats per minute
-
cardiac compromise
see acute coronary syndrome
-
cardiopulmonary resuscitation (CPR)
actions taken to revive a person by keeping the person's heart and lungs wroking
-
cardiovascular system
the heart and the blood vessels
-
congestive heart failure (CHF)
the failure of the heart to pump efficiently, leading to excessive blood or fluids in the lungs, the body, or both
-
coronoary artery disease (CAD)
diseases that affect the arteries of the heart
-
defibrillation
delivery of an electrical shock to stop the fibrillation of hear muscles and restore a normal heart rhythm
-
dyspnea
shortness of breath; labored or difficult breathing
-
dysrhythmia
a distrubance in heart rate and rhythm
-
edema
swelling resulting from a buildup of fluid in the tissues
-
embolism
blockage of a vessel by a clot or foreigm material brought to the site by the blood current
-
nitroglycerin (NTG)
a medication that dilates the blood vessels
-
occlusion
blockage, as of an artery by fatty deposits
-
pedal edema
accumulation of fluid in the feet or ankles
-
pulmonary edema
accumulation of fluid in the lungs
-
pulseless electrical activity (PEA)
-
a condition in which the heart's electrical rhythm remains relatively normal, yet the mechanical pumpin gactivity fails to follow the electrical activity. causing cardiac arrest
-
sudden death
a cardiac arrest that occurs within 2 hours of the onset of symptoms. the patient may have no prior symptoms of coronoary artery diesease
-
tachycardia
when the heart rate is fast, above 100 beats per min
-
thrombus
a clot formed of blood and plaque attached to the inner wall of an artery of vein
-
ventribular fibrillation (VF)
a condition in which the heart's electrical impulses are disorganized, preventing the heart muscle from contracting normally
-
ventricular tachycardia (v_tach)
-
- a condition in whihc the heartbeat is quite rapid; if rapid enough, ventricular tachycardia will not allow the heart's chambers to fill with enough blood between beats to produce blood flow sufficient to meet the body's needs
