A group of symptoms caused by myocardial ischemia; includes angina and myocardial
infarction. - ANSWER---acute coronary syndrome (ACS)
A heart attack; death of heart muscle following obstruction of blood flow to it. Acute in this
context means "new" or "happening right now." - ANSWER---acute myocardial infarction (AMI)
Transient (short-lived) chest discomfort caused by partial or temporary blockage of blood flow
to the heart muscle; also called angina - ANSWER---angina pectoris
the front surface of the body; the side facing you in the standard anatomical position -
ANSWER---anterior
the main artery, which receives blood from the left ventricle and delivers it to all the other
arteries that carry blood to the tissues of the body. - ANSWER---aorta
A weakness in the wall of the aorta that makes it susceptible to rupture. - ANSWER---aortic
aneurysm
The one-way valve that lies between the left ventricle and the aorta and keeps blood from
flowing back into the left ventricle after the left ventricle ejects its blood into the aorta; one of
four heart valves. - ANSWER---aortic valve
A tracing on an ECG that is the result of interference, such as patient movement, rather than
the heart's electrical activity. - ANSWER---artifact
the complete absence of all heart electrical activity - ANSWER---asystole

A disorder in which cholesterol and calcium build up inside the walls of the blood vessels,
forming plaque, which eventually leads to partial or complete blockage of blood flow. -
ANSWER---atherosclerosis
one of two upper chambers of the heart - ANSWER---atrium
The ability of cardiac muscle cells to contract without stimulation from the nervous system. -
ANSWER---automaticity
The part of the nervous system that controls the involuntary activities of the body such as the
heart rate, blood pressure, and digestion of food. - ANSWER---autonomic nervous system
slow heart rate (less than 60 bpm) - ANSWER---bradycardia
When the heart fails to generate effective and detectable blood flow; pulses are not palpable in
cardiac arrest, even if muscular and electrical activity continues in the heart. - ANSWER---
cardiac arrest
A measure of the volume of blood circulated by the heart in 1 minute, calculated by multiplying
the stroke volume by the heart rate. - ANSWER---cardiac output
A state in which not enough oxygen is delivered to the tissues of the body, caused by low
output of blood from the heart. It can be a severe complication of a large acute myocardial
infarction, as well as other conditions. - ANSWER---cardiogenic shock

A disorder in which the heart loses part of its ability to effectively pump blood, usually as a
result of damage to the heart muscle and usually resulting in a backup of fluid into the lungs. -
ANSWER---congestive heart failure (CHF)
The blood vessels that carry blood and nutrients to the heart muscle - ANSWER---coronary
arteries
To shock a fibrillating (chaotically beating) heart with specialized electrical current in an
attempt to restore a normal, rhythmic beat. - ANSWER---defibrillate
Swelling in the part of the body closest to the ground, caused by collection of fluid in the
tissues; a possible sign of congestive heart failure. - ANSWER---dependent edema
Widening of a tubular structure such as a coronary artery. - ANSWER---dilation
A condition in which the inner layers of an artery, such as the aorta, become separated,
allowing blood (at high pressures) to flow between the layers. - ANSWER---dissecting aneurysm
An irregular or abnormal heart rhythm - ANSWER---dysrrhythmia
An emergency situation created by excessively high blood pressure, which can lead to serious
complications such as stroke or aneurysm. - ANSWER---hypertensive emergency
Death of a body tissue, usually caused by interruption of its blood supply. - ANSWER---infarction
Below a body part or nearer to the feet - ANSWER---inferior

A lack of oxygen that deprives tissues of necessary nutrients, resulting from partial or complete
blockage of blood flow; potentially reversible because permanent injury has not yet occurred. -
ANSWER---ischemia
The inside diameter of an artery or other hollow structure - ANSWER---lumen
The heart muscle - ANSWER---myocardium
A blockage, usually of a tubular structure such as a blood vessel. - ANSWER---occlusion
The part of the autonomous nervous system that controls vegetative functions such as
digestion of food and relaxation - ANSWER---parasympathetic nervous system
The circulation of oxygenated blood within an organ or tissue in adequate amounts to meet the
cells' current needs. - ANSWER---perfusion
The back surface of the body; the side away from you in the standard anatomic position. -
ANSWER---Posterior
The return of a pulse and effective blood flow to the body in a patient who previously was in
cardiac arrest. - ANSWER---return of spontaneous circulation (ROSC)
The volume of blood ejected with each ventricular contraction - ANSWER---stroke volume
Above a body part or nearer to the head. - ANSWER---superior
