EKG Rhythm Interpretation Packet
EKG Rhythm Interpretation Packet
Instructions
Complete a review of the basics of the conduction system and electrocardiogram (EKG) readings, then
work through the steps of systematically interpreting EKG rhythms that follow. After completing these,
you will be presented with several opportunities to practice your interpretation skills. Analyze the strips
in the Rhythm Practice section and enter the related data below each.
Review of the Basics
Conduction system
Complete the labeling for the diagram below by naming each component. Place the correct name beside
the number in the list below the diagram. Refer to your text as needed.
1.Sinoatrial (SA) node 7. Purkinje Fibers
2. Internodal pathway 8. Left Posterior division
3. Arrow showing: Blood flow 9. Left Anterior Division
4. Atrioventricular (AV) Node 10. Left bundle branch
5.Bundle of His 11. Arrows showing: Bachmann’s Bundle

Electrocardiogram
The diagram that follows shows a normal sinus rhythm. Different aspects of the rhythm are labeled
(progressing from left to right):
The rhythm begins as straight, on the baseline.
Next, the PR Interval is identified with the upward bend of the P wave and a return to the
baseline – which is identified as the PR Segment.
The QRS Complex follows with the dip of the Q wave, followed by the spike of the R wave, and
completed with another dip – the S wave.
Another return to baseline, following the S wave and extending to the upward bend of the T
wave, is identified as the ST Segment.
The QT Interval begins with QRS Complex and extends to the end of the T wave.
After the T wave, there is a return to baseline.
