Vital Vocabulary
Show Answers:

  1. Acute myocardial infarction (AMI)
    Heart attach; death of heart muscle following obstruction of blood flow to it. Acute in this context means "new" or "happening right now."
  2. Angina pectoris
    Transient (short lived) chest discomfort caused by partial or temporary blockage of blood flow to the heart muscle.
  3. Anterior
    The front surface of the body; the side tacing you in the standard anatomic position.
  4. Aorta
    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.
  5. Aortic valve
    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 the four heart valves.
  6. Arrhythmia
    An irregular or abnormal heart rhythm
  7. Athrosclerosis
    A disorder in which cholesterol and calcium build up inside the walls of blood vessels, eventually leading to partial or complete blockage of blood flow.
  8. Asystole
    Complete absence of heart electrical activity
  9. Atrium
    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.
  10. Bradycardia
    Slow heart rate, less than 60 beats/min
  11. Cardiac arrest
    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
  12. 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. It can be a severe complication of a large acute myocardial infarction, as well as other conditions
  13. Congestive heart failure (CHF)
    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.
  14. Coronary artery
    A blood vessel that carries blood and nutrients to the heart muscles.
  15. Defibrillate
    To shock a fibrillating (chaotically beating) heart with specialized electrical current in an attempt to restore a normal rhythmic beat.
  16. 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.
  17. Dilation
    Widening of a tubular structure such as a coronary artery
  18. Infarction
    Death of a body tissue, usually caused by interruption of its blood supply
  19. Inferior
    The part of the body, or any body part , nearer to the feet.
  20. Ischemia
    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
  21. Lumen
    The inside diameter of an artery or other hollow structure
  22. Myocardium
    Heart muscle
  23. Occlusion
    Blockage, usually of a tubular structure such as a blood vessel.
  24. Perfusion
    The flow of blood through body tissues and vessels.
  25. Posterior
    The back surface of the body; the side away from you in the standard anatomical position.
  26. Superior
    The part of the body, or any body part, nearer to the head.
  27. Syncope
    Fainting spell or transient loss of consciousness.
  28. Tachycardia
    Rapid heart ryhthm, more then 100 beats/min
  29. Ventricle
    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 artery.
  30. Ventricular fibrillation
    Disorganized, ineffective twitching of the ventricles, resulting in no blood flow and a state of cardiac arrest.
  31. Ventricular Tachycardia (VT)
    Rapid heart rhythm in which the electrical impulse begins in the ventricle (instead of the atrium), which may result in inadequate blood flow eventually deteriorate into cardiac arrest
