October 26 - October 30: EKG Update Review Part 1 and 2, Introducing the Premature Junctional Contraction (PJC), Sinus Block and Sinus Arrest
OBJECTIVES:
Be able to correctly indentify and interpret all sinus rhythms, atrial rhythms and junctional rhythms learned in class so far
Be able to correctly identify and interpret the PAC
Be able to correctly identify and interpret the premature junctional contraction (PJC)
Be able to correctly identify and interpret a sinus block and a sinus arrest

Class, Please download the EXAM FIRST. We are working through MOST Exam questions in the YOUTUBE video lectures.

Note to Class: There are 4 Youtube Videos with this Week (see below...work through this page to the Sinus Block and Sinus Arrest YOUTUBE videos):

Please watch EKG Update Review Part 1 and Part 2 YOUTUBE videos.

I want you to interpret Worksheet #1 on YOUR OWN. This will give me feedback on how you are doing with your EKG interpretations. Suggest you do AFTER going over the Part 1 and Part 2 reviews

Class, here is the same Junctional Rhythm Worksheet you used last week (just as a reference sheet for you)

With SA Block the R-R interval measurement is within plus or minus 2 small boxes. Here is how you report a rhythm with a sinus block: NSR with a Sinus Block. Note how you do NOT have to state where the block is.
With SA Arrest the R-R interval measurement is greater than plus or minus 2 small boxes. Here is how you report a rhythm with a sinus arrest: NSR with a Sinus Arrest. Note how you do NOT have to state where the arrest is.
Note the Different Names of Junctional Rhythms, All determined by Heart Rate
Below are some examples of Junctional Rhythms with Hidden 'P' waves, Inverted 'P' waves, and 'P' waves after QRS complex
Introducing the Premature Atrial Contaction (PAC)
CLASS, REMENDER YOU REPORT THE UNDERLYING RHYTHM, RATE, P WAVES, PRI AND QRS TO THE LEFT (i.e., BEFORE) OF THE PAC! THEN STATE WHERE THE PAC IS; IN THIS CASE IT IS THE 7th COMPLEX.
Paroxysmal Rhythms Review
Paroxysmal means sudden onset. In class, whenever you see a rhythm 'suddenly' get significantly faster (100 b/min or faster) this is a paroxysmal rhythm. For class, we will ONLY identify a paroxysmal rhythm when we see it (like below). Often times our textbook author will say this is a 'paroxysmal rhythm', meaning the author wanted you to know it suddenly happened.
For the interpretation. Interpret a paroxysmal rhythm like TWO rhythms. Interpret the FIRST rhythm and then the Paroxysmal rhythm. Interpet like below: NSR into paroxysmal atrial tachycardia.
With atrial flutter the 'P' waves are 'flutter' waves. The PRI is indeterminate. Note the 'Flutter' or 'F' waves. They often look like a 'saw tooth' as well. Baseline is absent. Report the F wave to QRS ratio. If not a consistent ratio it is called Atrial Flutter with Variable AV conduction (as seen above).
