Junctional Rhythms
In the previous pages, we reviewed the rhythms originating in the SA node and the atria. Occasionally, these pacmaker sites fail and the next site within the conduction system takes over. In this case, the AV Node. Being the next highest site and rate, the atria will take over. In some cases, junctional arrhythmias are the result junctional irritability.
The four rhythms associated with the atria are
Junctional Escape Rhythm, Accelerated Junctional, Junctional Tachycardia, and Premature Junctional Contractions (PJC). Remember to use the five rules.
