  1. beginning of the heart formation in utero
    primitive heart tube
  2. continuation of the umbilical cord
    ductus venosus
  3. connects pulmonary artery with the descending thoracic aorta
    ductus arteriosus
  4. opening in the interatrial septum
    foramen ovale
  5. drains excess fluid in the pericardium
    pericardial window
  6. located in the R atrial wall, natural pacemaker
    Sinoatrial node (SA)
  7. node located in the atrial septum
    atrioventricular node AV
  8. located in the interventricular septum
    bundle of His
  9. disturbances in normal heart rhythm, decrease cardiac output, damage to the myocardium and leads to cardiac arrest
    cardiac dysrythmias
  10. most common, found in young adults and elderly, variation in heart beat, benign, no treatment
    sinus dysrhythmias
  11. 100BPM or more
    sinus tachycardia
  12. 60BPM or less
    sinus bradycardia
  13. amt of blood ejected from either the L or R ventricle in 1 beat
    cardiac output
  14. records the electrical activity of the heart
  15. represents atrial depolarization
    P wave
  16. represent ventricular repolarization
    T wave
  17. represents ventricular depolarization
