1. EKG Grid 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. Each large square has 5 small squares across SO 0.04 X
5 = 0.2 seconds

intervals
5. P Wave Atrial depolarization
6. PR Interval Normal is 0.12 to 0.20 seconds
Corresponds to the delay the AV node provides to allow for ventricular
filling
7. QRS Complex Normal is <0.12 seconds usually between 0.06 to 0.10 seconds
Ventricular depolarization
8. QT Interval Normal 0.36-0.46

6 Steps for Rhythm Determine Regularity
Interpre- tation
Calculate the Rate
Evaluate the P wave
Measure the PRI
10. Normal Evaluate the QRS
Sinus Width
Rhythm
Evaluate the T wave and Calculate the QTI
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
11. Sinus complex PRI : 0.12 to 0.20 seconds
Bradycar- dia QRS: 0.06 to 0.10 seconds
QTI: 0.36 to 0.46 seconds
wave: upright, smooth and round uniform shape
Regularity: atrial and ventricular rate are regular
Rate: < 60 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
wave: upright, smooth and round uniform shape
12. Sinus
Tachycar- dia Regularity: atrial and ventricular rate are
regular Rate: >100 beats per minute
P wave: upright, smooth, round and uniform shape, one for every QRS
