Accelerated Junctional Rhythm is a cardiac rhythm where electrical impulses originate from the atrioventricular (AV) junction at a rate faster than the typical intrinsic junctional rhythm. This accelerated rhythm may occur as a compensatory response to a slower or blocked sinus rhythm.
Heart Rate: 60 to 100 beats per minute
Rhythm: Regular
P wave: P wave is inverted
PR Interval: P wave occurs before the QRS complex
QRS: 0.11 sec or less unless adnormally conducted.
Accelerated Junctional Rhythm is diagnosed through an electrocardiogram (ECG) or continuous cardiac monitoring. Characteristic features include a heart rate faster than the intrinsic junctional rhythm, inverted or absent P waves, and a regular rhythm.
If the accelerated junctional rhythm is a result of reversible factors (e.g., medication side effects, electrolyte imbalances, ischemia), addressing these causes is important. Observation: In many cases, especially if the accelerated junctional rhythm is transient or asymptomatic, observation without immediate intervention may be appropriate. Pacemaker Therapy: In cases where the accelerated junctional rhythm is persistent, symptomatic, or associated with significant bradycardia, pacemaker therapy may be considered to restore a more normal cardiac rhythm.
