Wide-Complex Tachycardia: The Basics
Objectives
At the end of this chapter, the student should be able to:
- Describe the umbrella term wide-complex tachycardias (WCTs), and list the five groups that comprise them using the five-finger analogy. (pp 544, 545, 547)
- List some factors that create the wide morphology of the QRS complexes in the WCTs. (p 546)
- Discuss the concept of rate-related aberrancy and how the aberrancy is created. (pp 548–549)
- Discuss the diagnosis when examining a patient with preexisting bundle branch block or the presence of an intraventricular conduction delay. (pp 549–550)
- Discuss some of the entities and mechanisms related to the metabolic, physiologic, paced rhythm, or pharmacologic causes in the supraventricular tachycardias with aberrancy. (pp 550–552)
- Summarize the basic concepts involved in diagnosing and identifying ventricular tachycardias on a rhythm strip or ECG. (p 552)
