  1. aorta
    largest artery in the body
  2. arteriole
    small artery
  3. atrioventricular bundle (bundle of His)
    specialized muscle fibers connecting the atria with the ventricles and transmitting electrical impulses between them.
  4. atrioventricular node (AV node)
    specialized tissue in the wall between the atria. Electrical impulses pass from the pacemaker (SA node) through the AV node and the atrioventricular bundle or bundle of His toward the ventricles.
  5. capillary
    smallest blood vessel. Materials pass to and from the bloodstream through the thin capillary walls.
  6. diastole
    relaxation phase of the heartbeat. From the Greek diastole, dilation.
  7. pulmonary circulation
    flow of blood from the heart to the lungs and back to the heart.
  8. septum
    partition or wall dividing a cavity, such as between right and left atria (interatrial septum) and right and left ventricles (interventricular septum)
  9. sinoatrial node (SA node)
    pacemaker of the heart
  10. systemic circulation
    flow of blood from body tissue to the heart and then from the heart back to body tissues
  11. systole
    contraction phase of the heartbeat. From the Greek systole, a contracting.
  12. vena cava
    largest vein in the body. The superior and inferior venae cavae return blood to the right atrium of the heart
  13. ventricle
    one of two lower chambers of the heart
  14. venule
    small vein
  15. congenital heart disease
    abnormalities in the heart at birth
  16. congestive heart failure (CHF)
    heart is unable to pump its required amount of blood
  17. acute coronary syndromes (ACSs)
    conditions caused by myocardial ischemia; unstable angina and myocardial infaction (heart attack), which are consequences of plaque rupture in coronary arteries.
  18. endocarditis
    inflammation of the inner lining of the heart
  19. aneurysm
    local widening (dilation) of an arterial wall
  20. hypertension (HTN)
    high blood pressure
  21. holter monitoring
    an ECG device is worn during a 24-hour period to detect cardiac arrhythmias.
  22. stress test
    exercise tolerance test (ETT) determines the heart's response to physical exertion (stress)
  23. cardioversion
    technique using lower energy to treat atrial fibrillation, atrial flutter, and supraventricular tachycardia
  24. percutaneous coronary intervention (PCI)
    balloon-tipped catheter is inserted into a coronary artery to open the artery; stents are put in place.
  25. thrombolytic therapy
    drugs to dissolve clots are injected into the bloodstream of patients with coronary thrombosis
