An ECG strip shows a rhythm with normal P-R, P’s are 1:1 with
QRS complexes, rate 70, rhythm regular, QRS 0.14 sec.
What is the name of the rhythm?
![Page 4: Name this dysrhythmia:](https://reader035.fdocuments.us/reader035/viewer/2022062221/568145bd550346895db2c7b7/html5/thumbnails/4.jpg)
NSR with a bundle
![Page 5: Name this dysrhythmia:](https://reader035.fdocuments.us/reader035/viewer/2022062221/568145bd550346895db2c7b7/html5/thumbnails/5.jpg)
An ECG strip shows wide QRS complexes at a rate of 170. No P
waves are seen. One possible interpretation of this rhythm
is V Tach. What is another possible
interpretation?

Describe how the marks on the border of the ECG paper can be
used to determine heart rate.
![Page 8: Name this dysrhythmia:](https://reader035.fdocuments.us/reader035/viewer/2022062221/568145bd550346895db2c7b7/html5/thumbnails/8.jpg)
The marks are 3 seconds apart. Count the number of complexes in six seconds and multiply by
ten to find the heart rate.
