NUR417 EKG Rhythm Interpretation Study Guide and Practice Packet Latest Update with complete solution

EKG Rhythm Interpretation Packet Instructions Complete a review 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. SA node 2. Internodal pathway 3. Arrow showing: flow of cardiac impulse 4. AV node 5.

Arrows showing: flow of cardiac impulse 2 NUR417 Nursing Care of the Adult 2 EKG Rhythm Interpretation Packet 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.
