You get confident with rhythm first. That's something you can assess fairly accurately from the monitor. But maybe there's a normal rhythm hiding a heartbeat that's severely compromised. You've got to look inside the pattern to learn that. It's the waveform that communicates the integrity of the cycle. It tells you whether or not the impulse is following normal pathways.


The electrocardiogram provides a relatively simple tool for charting the very complex electrophysiology of the heart. In the acute care setting, one has to define any changes in conduction, some of which may be benign and some which signify significant disease.

ECG changes associated with intraventricular conduction are discussed in this program.

Topics that will be discussed are the normal process of synchronous ventricular activation, the anatomic differences of the bundle branches, the alteration of electrical forces with bundle branch block, the features and significance of right and left bundle branch block, the features of hemiblock, the differences of bifascicular, trifascicular and bilateral bundle branch block and the nursing implications associated with these intraventricular conduction disturbances.

To complete this course, you must do the following:

  • Read the Overview and Course Objectives.
  • Study the Terminology.
  • Read the course material.
  • Complete the Learning Activity.
  • Complete the Post Test with a score of 80% or more.

    The material is organized around the following categories:

  • The Normal Process of Synchronous Ventricular Activation
  • Anatomic Differences of Bundle Branches
  • Alteration of Electrical Forces with Bundle Branch Block
  • Features and Significance of Right and Left Bundle Branch Block
  • Features of Hemiblock
  • Differences of Bifasicular, Trifasicular, and Bilateral Bundle Branch Block
  • Conclusion

    The purpose of this program is to provide nurses an understanding of intraventricular conduction disturbances in performing cardiac monitoring for acute care, and steps for appropriate management.

    After completing this course, the learner should be able to:

  • Review the normal process of synchronous ventricular activation.
  • Compare the anatomic differences of the bundle branches, and describe the alteration of electrical forces that occurs with bundle branch block.
  • Discuss the features and significance of right bundle branch block.
  • Identify features of hemiblock.
  • Differentiate bifascicular, trifascicular, and bilateral bundle branch block.
  • Discuss the nursing implications of monitoring patients with existing or potential intraventricular conduction disturbances.
