Heart attack; death of heart muscle following obstruction of blood flow to it. Acute in this context means "new" or "happening right now."
acute myocardial infarction (AMI)
Transient (short-lived) chest discomfort caused by partial or temporary blockage of blood flow to the heart muscle.
angina pectoris
The front surface of the body; the side facing you in the standard anatomic position.
anterior
The principal artery leaving the left side of the heart and carrying freshly oxygenated blood to the body.
aorta
The one-way valve that lies between the left ventricle and the aorta. It keeps blood from flowing back into the left ventricle after the left ventricle ejects its blood into the aorta. One of four heart valves.
aortic valve
An irregular or abnormal heart rhythm.
arrhythmia
A disease that is characterized by hardening, thickening, and calcification of the arterial walls.
arteriosclerosis
Complete absence of heart electrical activity.
asystole
One of two (right and left) upper chambers of the heart. The right atrium receives blood from the vena cava and delivers it to the right ventricle. The left atrium receives blood from pulmonary veins and delivers it to the left ventricle.
atrium
A heart rate of less than 60 beats/min in children or less than 80 beats/min in infants.
bradycardia
A state in which the heart fails to generate an effective and detectable blood flow; pulses are not palpable in cardiac arrest, even if muscular and electrical activity continues in the heart.
cardiac arrest
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.
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.
congestive heart failure (CHF)
A blood vessel that carries blood and nutrients to the heart muscle.
coronary artery
To shock a fibrillating (chaotically beating) heart with specialized electrical current in an attempt to restore a normal rhythmic beat.
defibrillate
Widening of a tubular structure such as a coronary artery.
dilation
Completely disorganized, ineffective twitching of the heart muscle.
fibrillation
Death of a body tissue, usually caused by interruption of its blood supply.
infarction
The part of the body, or any body part, nearer to the feet.
inferior
A lack of oxygen that deprives tissues of necessary nutrients, resulting from partial or complete blockage of blood flow; potentially reversible since permanent injury has not yet occurred.
ischemia
The inside diameter of an artery or other hollow structure.
lumen
Blockage, usually of a tubular structure such as a blood vessel.
occlusion
Swelling of the feet and ankles caused by collection of fluid in the tissues; a possible sign of congestive heart failure (CHF).
pedal edema
The circulation of blood within an organ or tissue in adequate amounts to meet the cells' current needs.
perfusion
The back surface of the body; the side away from you in the standard anatomical position.
posterior
The part of the body, or any body part, nearer to the head.
superior
Rapid heart rhythm, more than 100 beats/min.
tachycardia
One of two (right and left) lower chambers of the heart. The left ventricle receives blood from the left atrium (upper chamber) and delivers blood to the aorta. The right ventricle receives blood from the right atrium and pumps it into the pulmonary arter
ventricle
Disorganized, ineffective twitching of the ventricles, resulting in no blood flow and a state of cardiac arrest.
ventricular fibrillation
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 into cardiac arrest.
ventricular tachycardia
