Identify specific cardiac dysrhythmias Describe appropriate nursing interventions for

specific dysrhythmias

Junctional Rhythms

Junctional rhythms are named such because their impulse originates from the AV node (AV junction) instead of the SA node.

The SA node may be impaired secondary to drug toxicity or underlying cardiac disease.

Characteristics of all Junctional Rhythms

Inverted (negative) or absent P waves are seen before each QRS complex OR

P wave can be hidden in the QRS complex OR

P wave may follow the QRS complex
