  1. if the R-R intervals are all equal the rhythm is
  2. if the R-R intervals are not equal the rhythm is
  3. p waves shows what kind of contraction
    atrial contraction
  4. atrial contraction is caused by the start of the impulse of the
    SA Node
  5. to get atrial contraction you have to have
    atrial depolarization
  6. what causes depolarization
    switching of electrodes (Na+ and K+) pumps

    (which carried the wave of current -- then causing depolarization which causes contraction
  7. QRS complex shows what type of contraction
    ventricular contraction or ventricular depolarization
  8. t-waves shows what type of repolarization?
    ventricular repolarization or relaxation
  9. impulse starts at the SA node, which is created by
    automaticity (pacemaker)
  10. impule travels through the inner nodule pathways to the
    AV node
  11. then goes through the
    bundle of his
  12. into bundle branches, to the
    perkinjie fibers
  13. list all thats in the ATRIA
    SA node -- inner nodule pathways -- AW node -- bundle of his
  14. list all thats in the VENTRICLES
    bundle branches and perkinjie fibers
  15. normal ranges of a PR interval
    .12 - .20 seconds
  16. the PR intervals represents
    SA node -- inner nodule pathways -- AV node -- through the end of the bundle of his
  17. any problem at the PR interval shows what kind of problem
    atrial problem
  18. normal ranges of a QRS complex
    .04 - .11 seconds
  19. t-waves occurs in the
    bundle branches and perkinjie fibers
  20. if all p waves look identical and all are up right like they are suppose to be then they are most likely called
    sinus = meaning it came from the SA node = sinoatrial node
  21. if p waves dont look identicals then they are called
    ectopic - which means anything else
