Cardiovascular System
Show Answers:

  1. Anaemia
    Reduction in the quantity of oxygen carrying blood cells (haemoglobin) in the blood
  2. Aneurysm
    Balloon-like swelling in the wall of an artery
  3. Angina
    Reduction of blood flow to the heart muscle (myocardium) in the coronary arteries
  4. Arrhythmia
    Any variation from the normal cardiac rhythm (normal sinus rhythm)
  5. Atrial
    Relating to the upper chambers of the heart (atria)
  6. Blood Pressure
    Pressure of blood in the arteries, usually measured in millimetres of mercury (mmHg)
  7. Bradycardia
    Slow heart rate, usually < 60 bpm
  8. Cardia/Cardiac
    Relating to the heart
  9. Cardiac Arrest
    The cessation of effective pumping action by the heart muscle
  10. Cyanosis
    A bluish discoloration of the skin and mucus membranes, resulting from a lack of oxygen (cyanosed)
  11. Defibrillation
    An electric shock administered to restore normal rhythm in cardiac arrest
  12. Diastole
    The period between contractions when the heart muscle relaxes (diastolic)
  13. Embolus
    A clot in an artery which obstructs the flow of blood (embolism)
  14. Epistaxis
    Bleeding from the nose
  15. Fibrillation
    A rapid, uncoordinated heart muscle (myocardium) action resulting in inadequate circulation
  16. Frank
    Fresh blood
  17. Haematoma
    Accumulation of blood within tissue (bruise)
  18. Haemorrhage
  19. Heart Block
    Impairment of normal electrical conduction in the heart
  20. Hypertension
    Elevation of arterial blood pressure above normal range (>140mmHg)
  21. Hypotension
    A decrease of arterial blood pressure below normal range (<100 mmHg)
  22. Hypovolemia
    Decreased volume of circulating blood
  23. Infarction
    Death of tissue as a result of inadequate oxygen supply
  24. Ischaemia
    Inadequate circulation of blood caused by constriction or blockage in blood vessels
  25. Myocardial
    Relating to the myocardium (heart muscle)
  26. Oedema
    Excessive accumulation of fluid in body tissue (eg. peripheral or pulmonary)
  27. Systole
    The period of the cardiac cycle durin which the heart muscle contracts (systolic)
  28. Tachycardia
    A fast heart rate, usually >100 bpm
  29. Thrombosis
    A blood clot (thrombus)
  30. Vasovagal
    A nerve response which causes a drop in blood pressure and heart rate leading to fainting (syncope)
  31. Ventricular Fibrillation
    A life threatening cardiac arrhythmia in which the heart quivers (like jelly) resulting in inadequate circulation
  32. Ventricular Tachycardia
    A life threatening cardiac arrhythmia in which the heart rate increases to a level where adequate circulation is not achieved
