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.
How does a LBBB normally look?
it will have a wide weird QRS and you will see terminal S waves in lead 1.
How does a Left anterior fascicular block look like?
rS complexes in leads II, III, aVF, and qR complexes in leads I and aVL
How does a right posterior fascicular block look like?
qR complexes in leads II, III, and aVF, and rS complexes in lead I
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
What does a first degree heart block look like?
When the PR interval is longer than 200 ms.
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.
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.
also THE PATTERN REPEATS.
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.
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.

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