    aneurysm
  34. arrhythmia in which the heart beats abnormally slowly, usually fewer than 60 beats per minute in a resting adult
    bradycardia
  35. arrhythmia in which there is a fast but regular rhythm, with the heart possibly beating up to 200 beats/minute
    tachycardia
  36. hardening and narrowing of an artery along with the loss of its elasticity
    arteriosclerosis
  37. form of arteriosclerosis characterized by the deposit of plaques containing cholesterol and lipids that narrows the lumen in the arteries
