  1. How Does a RBBB normally look?

    what leads should you normally look at to see terminal S waves to confirm?
    1- RsR prime appearence. M-shaped QRS

    2- terminal S waves are seen in leads 1, aVL, and V6.
  2. How does a LBBB normally look?
    it will have a wide weird QRS and you will see terminal S waves in lead 1.
  3. How does a Left anterior fascicular block look like?
    rS complexes in leads II, III, aVF, and qR complexes in leads I and aVL
  4. How does a right posterior fascicular block look like?
    qR complexes in leads II, III, and aVF, and rS complexes in lead I
  5. what are the 5 steps to identifying the underying rhythm?
    • 1- P wave- size shape and number
    • 2- qrs - shape and direction
    • 3-PR interval - duration
    • 4-regularity
    • 5-rate
  6. What does a first degree heart block look like?
    When the PR interval is longer than 200 ms.
  7. what does a second degree type 1 block look like?
    Irregular rhythm, with a prolonged R-R interval before the blocked P-wave and the qrs complex after the first unblocked P-wave.
  8. what is the classic way a second degree type 1 presents itself? (wenchebach)
    the PR interval gets longer and longer until a p wave is then followed by another pwave instead of a QRS complex with a normal PR. 

  9. what does a second degree type 2 look like?
    looks like a regular rhythm with every other P wave blocked. or it can be irregular with an irregular R-R somewhere between the blocked P wave.
  10. what does a third degree heart block look like?
    usually has a regular rhythm with consistat p-p and r-r. it will have a upright P-wave and a non-existant PR interval. can have a wide QRS.

    can have a non conducted P wave with no realationship between p and qrs waves.
  11. What are signs and symptoms metabolic alkalosis?
    nausea, vomiting, fast breathing or deep breathing , and lethargy. 

    • -excessive vomiting¬†
    • -laxitive use
    • - loss of potassium and sodium bicarbonate
    • - ingestion of baking soda
    • -alcohol abuse
  12. what are signs and symptoms of respiratory alkalosis?
    • happenes when you breathe to0 fast or too deep and carbon dioxide levels is too low
    • -Hyperventilation
    • -high fever
    • - hypoxia
    • -liver and lung disease
    • -high altitudes
