So I can LASER Focus your energy and thought, I divided the Sinus Rhythms into Sinus Rhythms One and Sinus Rhytms Two. Questions for Exam are provided in each video.

Sometimes the Sinus tachycardia rhythm is so fast the P waves are partially hidden in the T waves. This only happens with a Sinus tachycardia. When the P waves are partially hidden, the PRI is indeterminate. See Below.
Review: How to do the PRI and QRS Measurements with a 'Flat' S wave
In the PRI above there is no Q wave so going from the inflection of the Pwave to inflection of the Rwave you get a PRI of 5 small boxes (.2 seconds) = normal
The Flat 'S' wave poses a real challenge. Here are the steps:
1) Follow the Rwave until it reaches isoelectric or (as above) it starts to go toward the Twave
2) Mark the point where the Rwave begins to go towards the Twave
3) Move over 1 small box from your mark; that is the J point
4) You can now measure the QRS; for the above it is 3 small boxes (.12 seconds) = normal
The PRI above is 4.5 small boxes (.18 seconds) = normal
The Swave is not present due to the inverted Twave. Use the same technique as with the Flat 'S' Wave
1) Follow the Rwave until it reaches isoelectric: I have marked it with the red line
2) Move over 1 small box from where the Rwave reaches isoelectric: that is your J point
3) You can now measure the QRS; for the above it is 3 small boxes (.12 seconds) = normal
