Diagnosis
Junctional rhythm is diagnosed through an electrocardiogram (ECG) or continuous cardiac monitoring. Characteristic features include a heart rate originating from the AV junction, inverted or absent P waves, and a regular rhythm.
Junctional rhythm is a cardiac rhythm where the electrical impulses originate from the atrioventricular (AV) junction, typically due to the absence of impulses from the sinoatrial (SA) node. It is considered an escape rhythm when the SA node fails to generate impulses or when the impulses are blocked.
Heart Rate: 40 to 60 beats per minute
Rhythm: Regular
P wave: Inverted or absent P waves
PR Interval: If P waves are present (less than 0.12 seconds).
QRS: Typically normal (0.06-0.10 seconds)
Junctional rhythm is diagnosed through an electrocardiogram (ECG) or continuous cardiac monitoring. Characteristic features include a heart rate originating from the AV junction, inverted or absent P waves, and a regular rhythm.
If the junctional rhythm is a result of reversible factors (e.g., medication side effects, electrolyte imbalances, ischemia), addressing these causes is a crucial aspect of management. Pacemaker Therapy: In cases where the junctional rhythm is symptomatic, persistent, or associated with significant bradycardia, pacemaker therapy may be considered to restore a more normal cardiac rhythm. Antiarrhythmic Medications: In some instances, medications may be used to suppress junctional rhythms, especially if they are causing symptoms or hemodynamic compromise.
