A junctional rhythm is a type of arrhythmia (irregular heartbeat). If you have a junctional rhythm, your heart’s natural pacemaker, known as your sinoatrial (SA) node, isn’t working as it should.

Feb 18, 2025 · 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.

The most common rhythm arising in the AV node is junctional rhythm, which may also be referred to as junctional escape rhythm. Junctional tachycardia is less common.

If the complex is late, it is called a junctional escape beat. To determine if a complex is early or late, we need to see at least two beats in a row of the underlying rhythm to establish its regularity.

Jun 11, 2025 · An accelerated junctional rhythm (rate >60 bpm) is a narrow complex rhythm that often supersedes a clinically bradycardic sinus node rate (see images below). The QRS complexes are …

Explore junctional rhythm in ECGs, its common causes, and differences from sinus rhythm. Learn about upper, middle, and lower junctional rhythms, and frequency analysis.

Mar 29, 2023 · Junctional rhythm is an irregular heart rhythm that stems from a natural pacemaker in the heart known as the atrioventricular junction. The heart has several built-in pacemakers that help …

Junctional rhythm is seen equally in men and women, and can be seen intermittently in young children and athletes, especially during sleep. It occurs commonly in patients with sinus node dysfunction. …

Aug 4, 2025 · A junctional rhythm is a type of abnormal heartbeat, or arrhythmia. It is usually not serious, although it can be associated with heart inflammation or recent heart surgery.

Nov 8, 2021 · With junctional rhythms, the impulse is initiated in the AV junction. This impulse point results in a backward or retrograde flow of electricity during atrial depolarization.
