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


  1. blood is forced OUT of the heart
    systole (strongest)
  2. blood fills the ventricles
    diastole (weakest)
  3. these collect blood
    atria
  4. these pump blood out from the heart
    ventricles
  5. right side pump deals with the
    lungs
  6. left side pump deals with the
    rest of the body besides the lungs
  7. pacemaker
    SA node
  8. the atria contract when (nodes)
    SA to AV node
  9. the ventricles contract when
    His to Purkinje
  10. which wave is depolarization, contraction of atria?
    P wave
  11. which wave is contraction of ventricles, depolarization?
    QRS
  12. which wave is recovery (repolarization)?
    T wave
  13. occlusion
    blockage
  14. 3 layers of pericardium
    • endo
    • myo
    • epi
  15. aneurysm/o **
    widening, widened blood vessel
  16. ather/o
    fatty plaque
  17. embol/o
    plug
  18. sept/o
    septum
  19. sphygm/o
    pulse
  20. -sphyxia
    pulse
  21. sten/o
    narrowing
  22. blood clot that obstructs a vessel
    thrombus
  23. when a thrombus travels through the vessels it is called
    an embolus
  24. removal of innermost wall of artery
    endarterectomy
  25. any dz that interferes with the ability of coronary arteries to deliver sufficient blood to the myocardium
    coronary artery disease
  26. area of tissue that undergoes necrosis after cessation of blood supply
    infarct
  27. angina
    chest pain
  28. balloon acronym
    PTCA: percutaneous transluminal coronary angioplasty
  29. CABG
    coronary artery bypass graft (uses vein)
  30. small masses of fibrin and platelets from bax lodging in weakened heart tissue
    vegetations
  31. enlarged, twisted superficial veins
    varicose veins
  32. when vein valves aren't working you get
    varicose veins
  33. another word for "not working" (like vein valves in varicose veins)
    incompetent
  34. soft blowing sound/murmur
    bruit
  35. coarctation
    narrowing of a vessel (aorta)
  36. quivering/spontanous muscle contrax causing ineffectual contrax
    fibrilliation
  37. palpitation
    sense that heart is not beating normally (can include many)
  38. when blood from the aorta goes into the pulmonary artery (because it didn't close at birth)
    patent ductus arteriosis
  39. circulation of blood through tissues
    or
    passage of fluids through vessels of an organ
    perfusion
  40. reduction of the LUMEN caused by smooth muscle contraction
    vasoconstriction
  41. widening of the LUMEN caused by smooth muscle relaxation
    vasodilation
  42. blood flows (slowly, quickly) through capillaries
    slowly--gives it time to make the gas exchange
  43. hardened plaque
    atherosclerosis
  44. bulge that might rupture
    aneurysm
  45. hollow thin mesh tube placed in artery after angioplasty to keep it open
    stent
  46. ischemia
    oxygen deprivation
  47. troponin T
    troponin I
    creatinine kinase
    these three are
    cardiac enzymes
  48. how do cardiac enzymes help dx MI?
    they do predictable things at certain intervals after MI.
  49. endocarditis can be ____ or _____
    infective (microbes) or noninfective (thrombi).
  50. backflow of blood (through a valve when there shouldn't be)
    regurgitation
  51. small masses of fibrin and platelets in weakened heart tissue (because of bax)
    vegetations
  52. vegetations collect on the valves, causing
    backflow, regurgitation
  53. what happens in varicose veins?
    valves are incompetent, allows backflow, bulge
  54. primary tumor of the heart
    myxoma (mucous connective tissue)
