2021年11月8日 · Junctional Rhythm aka Junctional “Escape” Rhythm is aptly named due to the electrical impulses causing the atrial activity are originating in the AV Junction. The rate for this rhythm is the same as the AV Junction, 40 – 60 bpm.

Junctional and ventricular escape rhythms arise when the rate of supraventricular impulses arriving at the AV node or ventricle is less than the intrinsic rate of the ectopic pacemaker. Conditions leading to the emergence of a junctional or ventricular escape rhythm include:

Learn about junctional rhythm and junctional tachycardia, particularly ECG diagnosis, etiology, differential diagnosis, clinical features and management.

2024年10月8日 · Accelerated junctional rhythm (AJR) occurs when the rate of an AV junctional pacemaker exceeds that of the sinus node. This situation arises when there is increased automaticity in the AV node coupled with decreased automaticity in the sinus node.

2020年7月5日 · The key characteristic of a junctional rhythm is an abnormal P rate. The P rate will be either absent, inverted, in the wrong place, or with a very short PR interval. When you encounter an EKG strip on a test, looking for those abnormal P wave conditions can help you identify a rhythm as junctional.

The strip below shows a junctional rhythm with retrograde P waves seen just before the QRS complex. The second rhythm strip shows retrograde P waves just after the QRS complex.

A basic rhythm strip showing junctional rhythm in Lead II. The junctional pacemaker is located between the atria and the ventricles, and the resulting P wave is caused by retrograde conduction through the atria.

2018年6月4日 · Here’s a picture of an ECG/EKG strip, showing 2 junctional beats. (Source) Note: This strip includes Normal rhythms and complexes, but include 2 PJCs. The second and 7th QRS complexes are missing P-waves, and are PJCs. This is SR with 2 PJC. There may also be a pause after the PJC.
