Accelerated junctional rhythm results from enhanced automaticity, increased sympathetic nervous system activity (catecholamines) or ischemia. Key features of this rhythm include a rate between 60-100 / minute, inverted or absent P waves (in lead II) , shortened PR interval, and QRS complexes that are usually narrow.
Accel Junctional.mp4DIAGNOSIS
DIAGNOSIS
Heart Rate (60-100 bpm) P Waves Absent, inverted (due to retrograde atrial depolarization), or appearing after the QRS complex or no Visible P Waves.
QRS Complex: Narrow (normal, <120 ms)
TREATMENT
TREATMENT
For medications, atropine can be used if the rhythm causes bradycardia, while calcium channel blockers may help if anxiety triggers the rhythm. Electrophysiological interventions are recommended for persistent symptoms unresponsive to medication
