Junctional rhythm also called nodal rhythm [2] describes an abnormal heart rhythm resulting from impulses coming from a locus of tissue in the area of the atrioventricular node (AV node), [3] the "junction" between atria and ventricles.

2022年5月20日 · A junctional rhythm happens when your heart’s natural pacemaker isn’t working. It’s usually not serious, but can make you feel tired or short of breath. Treatment can help.

In this article, you will learn about rhythms arising in, or near, the atrioventricular (AV) node. 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.

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:

atrioventricular junctional rhythm a junctional rhythm originating in the bundle of His, with a heart rate of 40 to 60 beats per minute; called also nodal rhythm.

Just before the impulse from the SA node reaches the AV junction, the AV junction generates its own impulse. Explore junctional rhythm in ECGs, its common causes, and differences from sinus rhythm. Learn about upper, middle, and lower junctional rhythms, and frequency analysis.

Supraventricular rhythms appear on an electrocardiogram (ECG) as narrow complex rhythms, which may be regular or irregular. They may have a normal rate, be tachycardic, or be bradycardic depending on the underlying arrhythmia mechanism and presence of atrioventricular (AV) nodal block.

2020年5月17日 · Junctional rhythm describes a heart-pacing fault where the electrical activity that initiates heart muscle contraction starts in the wrong region. Heart rhythm is the result of electrical impulses sent from the pacemaker cells of the sinoatrial node (SAN) at the top of the right atrium.

2023年3月29日 · 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...

The junctional rhythm initiates within the AV nodal tissue. Accelerated junctional rhythm is a result of enhanced automaticity of the AVN that supersedes the sinus node rate. During this...
