The analysis of dysrhythmias is an important part of the care of cardiac patients.  While many professionals take a basic class and begin reading monitors, there are numerous rhythms which were not covered in that initial class or that require a higher level of knowledge to interpret. 

As a result of completing this seminar, the nurse will have a more comprehensive understanding of basic rhythms and be able to recognize more advanced rhythms including wide complex ones which will require the use of the 12-lead ECG.

The nurse will also be able to correlate dysrhythmias with clinical presentation, significance and treatment options.

Some of the advanced rhythms covered include:

  • AV dissociation
  • Parasystoles
  • Aberration
  • Rate dependent BBB
  • AV nodal reentry
  • Wolf-Parkinson-White
  • Wide complex tachycardias
  • Pacemaker rhythms



This seminar reviews the physiology involved in the electrical system of the heart and then explains the mechanism behind the formation of rhythms. Participants will get a more advanced understanding of some of the basic rhythms learned before and some rarely seen (or not recognized) rhythms.

Other rhythms include some of the more difficult ones such as AV dissociation, parasystoles, aberration and rate dependent bundle branch blocks. In addition, some aspects of 12-lead ECG interpretation will be reviewed and then applied to the interpretation of supraventricular and ventricular tachycardias, including those involving accessory pathways. Pacemaker rhythms are reviewed such as normal function, problems with sensing and capture, and biventricular pacing.


(Please note:  This seminar is an advanced level session.  Participants should understand dysrhythmias prior to attending.  Basic knowledge of 12-lead ECG interpretation is also helpful but not mandatory.)

Recent seminar participants had this to say about
“Advanced Dysrhythmias”

“This was a great review which will enable me to provide better care for my cardiac patients.  I have been reading rhythms for a long time and I finally understand some I had been having trouble with.”

“I enjoyed this class very much.  It was a great refresher of many rhythms commonly seen with an advanced understanding of them.  Some of the advanced rhythms, I have seen but was unable to recognize.”

“Fantastic refresher course with advanced material presented to further my knowledge.  Very interesting and educational and presented in a way I could understand it!” 

“I was not aware of some of these types of rhythms, but I know we do see them in our patients.  This is a complex topic that I will definitely go back and review and then continue to look at rhythm strips.  Thank you for presenting this class!” 

“Thank you for a very professional and excellent class!  I gained a lot of knowledge in this session that I will continue to develop.  I never realized how important looking at multiple leads was in rhythm analysis!”
