The flashcards below were created by user kpierce2 on FreezingBlue Flashcards. What would you like to do?


  1. What does the cardiovascular system (CVS) consist of?
    heart, blood vessels (arteries, veins, and capillaries)
  2. Structure
    interior (atria and ventricles, septum, valves), walls (myocardium, pericardium, etc.) 
  3. Conduction
    • Has own O system, would continue beating outside of body, nodes and bundles and fibers oh my!
    • SA node-pacemaker sends to AV node
  4. Circulation: arteries, veins, and capillaries
    • Arteries: thick, muscular, and elastic for surge of blood, can feel pulses at arteries
    • Veins: less elastic and muscular, blood pressure too low to push blood on own, get help (where valves leak are varicose veins)
    • Capillaries: very tiny, very thin walls, only one cell thick, embedded in organs, feed walls of arteries and veins
  5. constricto
    to draw together
  6. dilato
    to expand
  7. angio AND vasculo AND vaso
    vessel
  8. aorto
    aorta
  9. arterio
    artery
  10. athero
    faty debris; fatty plaque
  11. cardio
    heart
  12. echo
    sound
  13. isch
    hold back
  14. phlebo
    vein (phlebotomist- take blood)
  15. brady
    fast
  16. tachy
    slow
  17. ectopy
    extra beat
  18. veno
    vein
  19. Pulses:
    • temporal (head)
    • radial (wrist)
    • femoral (groin)
    • carotid (neck)
    • brachial (elbow)
    • popliteal (behind knee)
    • dorsalis pedis (top of foot)
  20. BP
    blood pressure
  21. CAD
    coronary artery disease
  22. CCU
    coronary care unit
  23. CHF, what's the appropriate term?
    congestive heart failure, now just HF
  24. CPR
    cardiopulmonary resucitation
  25. CABG
    coronary artery bypass graft-- # corresponds to how many veins grafted
  26. AAA
    abdominal aortic aneurysm: damage done to distal body part
  27. ECG; EKG
    echocardiogram
  28. MI/STEMI
    • myodcardial infarction= acute coronary syndrome
    • if it's ischemic than STEMI: ST elevated myocardial infarction
    • if not ischemic, than NST angina
  29. TIA
    transient ischemic attack-- ministroke
  30. PCI
    percutaneous cardiac intervention
  31. Echocardiogram gives what?
    ejection fraction
  32. Process of plaque and 90 minute window
    Plaque closes off vessel to heart or break off and travel, gets clogged, O closed off--go in with endovascular into coronary arteries, place stint to allow blood flow-- we have 90 min to return O to ischemic muscle--otherwise stunning will turn to death
