EKG Grid - correct answer - Each small square (the smaller
lighter boxes within the big bold boxes) represents 0.04 seconds
Each larger square (the boxes within the bold lines) represents
0.2 seconds.
, Page | 2
Each large square has 5 small squares across SO 0.04 X 5 = 0.2
seconds
The 6 Second Strip Method - correct answer - Least accurate, but
quickest way to estimate rate especially in irregular rhythms
EKG - correct answer -
EKG intervals - correct answer -
P Wave - correct answer - Atrial depolarization
PR Interval - correct answer - Normal is 0.12 to 0.20 seconds
Corresponds to the delay the AV node provides to allow for
ventricular filling
QRS Complex - correct answer - Normal is <0.12 seconds usually
between 0.06 to 0.10 seconds
, Page | 3
Ventricular depolarization
QT Interval - correct answer - Normal 0.36-0.46
6 Steps for Rhythm Interpretation - correct answer - Determine
Regularity
Calculate the Rate
Evaluate the P wave
Measure the PRI
Evaluate the QRS Width
Evaluate the T wave and Calculate the QTI
Normal Sinus Rhythm - correct answer - Regularity: atrial and
ventricular rate are regular
Rate: 60 to 100 beats per minute
P wave: upright, smooth, round and uniform shape, one for every
QRS complex
PRI : 0.12 to 0.20 seconds
QRS: 0.06 to 0.10 seconds
QTI: 0.36 to 0.46 seconds
T wave: upright, smooth and round uniform shape
